  Log Message:
  -----------
  [CIR][AMDGPU] Add support for AMDGCN cos builtins (#197806)

Adds codegen for the following AMDGCN cos builtins:

- __builtin_amdgcn_cosf (float)
- __builtin_amdgcn_cosh (half)
- __builtin_amdgcn_cos_bf16 (bfloat16)

These are lowered to the corresponding `llvm.amdgcn.cos` intrinsic.
