This patch and its counterpart in oneapi-src/unified-runtime#1410 add CMake support for fetching an individual Unified Runtime adapter's source code from a different repo/tag combination using the new `fetch_adapter_source()` CMake function. Only the source is cloned, it is not added to the build directly. Instead, the path to the adapter source is passed into Unified Runtime clone described by the `UNIFIED_RUNTIME_REPO` and `UNIFIED_RUNTIME_TAG` CMake variables. This clone is the source of truth for the Unified Runtime API and drives the build of the external adapter source. Using `fetch_adapter_source()` is optional.

Implement `seq_cst` RC11/ptx6.0 memory consistency for CUDA backend. See https://dl.acm.org/doi/pdf/10.1145/3297858.3304043 and https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#memory-consistency-model for full details. Requires sm_70 or above. With this PR there is now a complete mapping between SYCL memory consistency model capabilities and the official CUDA model, fully exploiting CUDA capabilities when possible on supported arches. This makes the SYCL-CTS atomic_ref tests fully pass for sm_70 on the cuda backend. Fixes #11208 Depends on #12907 --------- Signed-off-by: JackAKirk <jack.kirk@codeplay.com>
