Commit Message

Metal: add GPU pointer support via untracked hazard mode and residency sets (#713)

Switch all Metal resources to MTLHazardTrackingModeUntracked and MTLStorageModeShared (replacing Managed), synchronize encoder transitions with MTLFence wait/update pairs, and track allocations in an MTLResidencySet committed before each submit. This enables GPU virtual addresses (gpuAddress) to be used as shader-visible pointers in argument buffers, which is required for Slang's pointer parameter support on Metal.

Requires Apple Silicon (GPU Family 6+) and macOS 15+ / iOS 18+. Bumps Metal C++ headers from macOS 14.2 to macOS 15.2 for the MTLResidencySet API. Adds Metal to the bind-pointers test suite with new test cases for ParameterBlock and struct-copy patterns.

Part of implementing shader-slang/slang#10841
