Support separate depth and stencil attachments during dynamic rendering.
- MVKRenderSubpass add separate getDepthFormat() & getStencilFormat(), and isDepthAttachmentUsed() & isStencilAttachmentUsed() and use instead of testing pixel format for depth and stencil components. - Add MVKRenderingAttachmentIterator class to consistently iterate, and take actions, on the attachments in VkRenderingInfo to create synthetic MVKRenderPass and extract image views and clear colors. - Remove mvkCreateRenderPass() and mvkCreateFramebuffer() in favor of additional constructors, and remove mvkGetDepthStencilFormat() in favor of retrieving formats for separate depth and stencil attachments. - MVKRenderpass constructors reorganize order of adding attachments and subpasses, and connecting the two. - Renmame MVKRenderPassAttachment to MVKAttachmentDescription. - MVKPipeline reorganize member variables to minimize gaps in content and remove unnecessary _isRasterizingDepthStencil member var (unrelated).

Fix Metal validation errors with dynamic rendering.
- MVKPipeline validate depth & stencil formats before setting frag shader depth and stencil builtins, and before setting formats in MTLRenderPipelineDescriptor. - MVKCmdClearAttachments always set depth/stencil format if subpass includes a depth or stencil attachment, even if they are not being cleared. - MVKRenderingAttachmentIterator add synthetic attachment if depth or stencil attachment is not provided, but image format supports both depth and stencil.

Deprecate the obsolete and non-standard VK_MVK_moltenvk extension.
The VK_MVK_moltenvk extension has never been brought inside Vulkan, and the functions have never been supported by the Vulkan Loader and Layers. Most of the functionality has long been replaced by the official VK_metal_objects extension. - Remove VK_MVK_moltenvk as an advertised extension. - Refactor vk_mvk_moltenvk.h header file into separate headers files: - mvk_config.h - Valid public config functions - mvk_private_api.h - Valid development debugging functions used with care - mvk_deprecated_api.h - Formally deprecated functions. - Retain skeleton vk_mvk_moltenvk.h header file for legacy compatibility only. - Update documentation and header comments to explain changes.

Advertise the VK_EXT_shader_demote_to_helper_invocation extension.
As of macOS Big Sur and iOS/tvOS 14, the `discard_fragment()` function in MSL is defined to have demote semantics; that is, fragment shader output is discarded, but the fragment shader thread continues to run as a helper invocation. This is very useful for Direct3D emulation, since this is the semantic that HLSL `discard` has. Signed-off-by: Chip Davis <chip@holochip.com>

- When forcing the window system to use the same high-power GPU as the app, move the call to MTLCreateSystemDefaultDevice() to MVKDevice constructor, instead of MVKDevice::createSwapchain(), and test whether the VK_KHR_swapchain extension is enabled to determine the need to swap GPUs. - After calling MTLCreateSystemDefaultDevice() the GPU will already be the same high-power GPU, so remove attempting to replace the MTLDevice. - Remove MVKPhysicalDevice::replaceMTLDevice() as no longer used. - Remove many unnecessary inline declarations in MVKDevice.h (unrelated).

Implemented Deferred Host Operations
Implemented deferred host operations in this commit. It was pretty simple with nothing Metal specific. I am a bit concerned on the return types of MVKDeferredOperation::join and about how to store the operation to be executed for later.

Made some fixes for Deferred Operations
The changes are as follows: * Moved the code around to fit with the ordering system * Added a function to get available cpu cores * Renamed variables with _ in front of them * Added mutexes and lock guards for the getters and setters of the max concurrency and result variables * Made max concurrency dynamic by returning 0 when the operation is finished

Support the
VK_EXT_4444_formats
extension.This turned out to be a little bit more involved than I had hoped. But, with this, we can now use the `VK_FORMAT_A4R4G4B4_UNORM_PACK16` and `VK_FORMAT_A4B4G4R4_UNORM_PACK16` formats from shaders, use them as blit sources, and even clear them. Storage images and render targets of these formats aren't supported, however. To support the latter would require the insertion of a swizzle into the fragment shader before returning. The former cannot be reasonably supported.

Support the
VK_EXT_calibrated_timestamps
extension.This extension has a direct Metal equivalent in the `-[MTLDevice sampleTimestamps:gpuTimestamp:]` method. However, that method returns CPU timestamps in the Mach absolute time domain, which is *not* that of `CLOCK_MONOTONIC_RAW` but of `CLOCK_UPTIME_RAW`. The function that corresponds to `CLOCK_MONOTONIC_RAW` is `mach_continuous_time()`. Therefore, this implementation uses the `mach_continuous_time()` function for the CPU timestamp. Perhaps we should lobby the WG for `VK_TIME_DOMAIN_CLOCK_UPTIME_RAW_EXT`.

Add support for VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN.
To reduce complexity and repetitive copy-pasted spaghetti code, the design approach here was to implement triangle fan conversion on MVKCmdDrawIndexedIndirect, as the most general of the draw commands, and then populate and invoke a synthetic MVKCmdDrawIndexedIndirect command from the other draw commands. - Rename pipeline factory shader cmdDrawIndexedIndirectMultiviewConvertBuffers() to cmdDrawIndexedIndirectConvertBuffers, and in addition to original support for modifying indirect content to support multiview, add support for converting triangle fan indirect content and indexes to triangle list. - Modify MVKCmdDrawIndexedIndirect to track need to convert triangle fans to triangle list, and invoke kernel function when needed. - Modify MVKCmdDraw, MVKCmdDrawIndexed, and MVKCmdDrawIndirect to populate and invoke a synthetic MVKCmdDrawIndexedIndirect command to convert triangle fans to triangle lists. - Add pipeline factory shader cmdDrawIndirectPopulateIndexes() to convert non-indexed indirect content to indexed indirect content. - MVKCmdDrawIndexedIndirect add support for zero divisor vertex buffers potentially coming from MVKCmdDraw and MVKCmdDrawIndexed. - Rename pipeline factory shader cmdDrawIndexedIndirectConvertBuffers() to cmdDrawIndexedIndirectTessConvertBuffers() so it will be invoked from MVKCommandEncodingPool::getCmdDrawIndirectTessConvertBuffersMTLComputePipelineState() (unrelated).

Support the
VK_KHR_incremental_present
extension.This extension allows apps to provide a hint to the presentation engine indicating which parts of the surface need updating. To provide this hint, we call `-[CALayer setNeedsDisplayInRect:]`, which indicates that only the given rectangle needs updating. I'm not sure if this will have any effect, especially if `CAMetalLayer.presentsWithTransaction` is `NO`. Luckily for us, this is only a hint, and it is permissible for the presentation engine to do nothing with the hint. The tests don't work because they apparently can't handle `VK_SUBOPTIMAL_KHR` being returned.

Support the
VK_EXT_pipeline_creation_feedback
extension.This provides feedback that indicates: * how long it took to compile each shader stage and the pipeline as a whole; * whether or not the pipeline or any shader stage were found in any supplied pipeline cache; and * whether or not any supplied base pipeline were used to accelerate pipeline creation. This is similar to the performance statistics that MoltenVK already collects. Since we don't use any supplied base pipeline at all, this implementation never sets `VK_PIPELINE_CREATION_FEEDBACK_BASE_PIPELINE_ACCELERATION_BIT`. However, I've identified several places where we could probably use the base pipeline to accelerate pipeline creation. One day, I should probably implement that. Likewise, because we don't yet support using `MTLBinaryArchive`s, `VK_PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT` is never set on the whole pipeline, though it *is* set for individual stages, on the assumption that any shader found in a cache is likely to be found in Metal's own implicit cache. In this implementation, shader stage compilation time includes any time needed to build the `MTLComputePipelineState`s needed for vertex and tessellation control shaders in tessellated pipelines. This patch also changes compilation of the vertex stage `MTLComputePipelineState`s in tessellated pipelines to be eager instead of lazy. We really ought to have been doing this anyway, in order to report pipeline failures at creation time instead of draw time. I'm not happy, though, that we now pay the cost of all three pipeline states all the time, instead of just the ones that are used. This also gets rid of some fields of `MVKGraphicsPipeline` that were only used during pipeline construction, which should save some memory, particularly for apps that create lots of pipelines.

Fix sync delay between calls to vkQueueSubmit() on non-Apple-Silicon …
…devices. The [MTLDevice sampleTimestamps:gpuTimestamp:] function turns out to be synchronized with other queue activities, and can block GPU execution if it is called between MTLCommandBuffer submissions. On non-Apple-Silicon devices, it was called before and after every vkQueueSubmit() submission, to track the correlation between GPU and CPU timestamps, and was delaying the start of GPU work on the next submission (on Apple Silicon, both CPU & GPU timestamps are specified in nanoseconds, and the call was bypassed). Move timestamp correlation from vkQueueSubmit() to vkGetPhysicalDeviceProperties(), where it is used to update VkPhysicalDeviceLimits::timestampPeriod on non-Apple-Silicon devices. Delegate MVKPhysicalDevice::getProperties(VkPhysicalDeviceProperties2*) to MVKPhysicalDevice::getProperties(VkPhysicalDeviceProperties*), plus minimize wasted effort if pNext is empty (unrelated). Move the declaration of several MVKPhysicalDevice member structs to potentially reduce member spacing (unrelated).
