Michael Jones b4be954856 Cycles: Simplify Metal backend with direct bindless resource encoding
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
