Cycles: enable Metal GPU rendering
This adds the remaining bits to enable Metal on macOS. There are still
performance optimizations and other improvements planned, but it should
now be ready for early testing.
This is currently only enabled on in Arm builds for M1 GPUs. It is not
yet working on AMD or Intel GPUs.
