  -----------
  [HLSL][SPIRV] Added clamp intrinsic (#113394)

Fixes #88052

- Added the following intrinsics:
  - `int_spv_uclamp`
  - `int_spv_sclamp`
  - `int_spv_fclamp`
- Updated DirectX counterparts to have the same three clamp intrinsics.
- Update the clamp.hlsl unit tests to include SPIRV
- Added the SPIRV specific tests
