Add Metal support for WaveGetActiveMask and WaveActiveCountBits (#8218)
## Summary
- Add Metal platform support for `WaveGetActiveMask()` and
`WaveActiveCountBits()` wave intrinsics
- Update capability requirements to include Metal platform for subgroup
ballot operations
- Implement Metal-specific intrinsic assembly using `simd_ballot()` and
`simd_vote` APIs
## Changes
- **source/slang/hlsl.meta.slang**:
- Add Metal target case for `WaveGetActiveMask()` using
`simd_ballot(true)`
- Update capability requirements from `cuda_glsl_hlsl_spirv` to
`cuda_glsl_hlsl_metal_spirv` for wave ballot functions
- **source/slang/slang-capabilities.capdef**:
- Add `metal` to `subgroup_ballot_activemask` capability alias
