Revert "Reland gpu: Add disk caching for skia generated shaders in OOP-R."

This reverts commit c2667e3.

Reason for revert: Only the first part made it to M69, without the subsequent patches this is just unnecessary overhead.

Original change's description:
> Reland gpu: Add disk caching for skia generated shaders in OOP-R.
>
> This reverts commit f9395d7.
>
> Use the GrContextOptions::PersistentCache API provided by skia to
> persist shaders generated internally by skia for OOP raster to disk.
> This requires using a special client id to namespace these shaders,
> similar to the one used by the InProcessCommandBuffer for viz.
>
> While the shaders for different sources are stored seperately on disk,
> they are finally merged into a single memory cache in the GPU process. In
> order to maintain a seperate cache for skia generated shaders, this also
> plumbs the client id for a loaded shader to the GPU process.
