  -----------
  [CIR][AMDGPU] Add support for AMDGCN class builtins (#213496)

Adds codegen for the following AMDGCN class builtins:

- __builtin_amdgcn_class (double)
- __builtin_amdgcn_classf (float)
- __builtin_amdgcn_classh (half)

These are lowered to the corresponding `llvm.amdgcn.class` intrinsics.
