This re-applies pull request #140671, but with a fix for #144713 where the
non-pointer part of IntegratorStateGPU was not initialized.
This PR is a more extensive follow on from #123551 (removal of AMD and Intel
GPU support).
All supported Apple GPUs have Metal 3 and tier 2 argument buffer support.
The invariant resource properties `gpuAddress` and `gpuResourceID` can be
written directly into GPU structs once at setup time rather than once per
dispatch. More background info can be found in this article:
https://developer.apple.com/documentation/metal/improving-cpu-performance-by-using-argument-buffers?language=objc
Code changes:
- All code relating to `MTLArgumentEncoder` is removed
- `KernelParamsMetal` updates are directly written into
`id<MTLBuffer> launch_params_buffer` which is used for the "static"
dispatch arguments
- Dynamic dispatch arguments are small enough to be encoded using the
`MTLComputeCommandEncoder.setBytes` function, eliminating the need for
cycling temporary arg buffers
