[HLSL] Expose half types and intrinsics always
We previously made an implmenetation error when adding `half` overloads for HLSL library functionalitly. The `half` type is always defined in HLSL and `half` intrinsics should not be conditionally included. When native 16-bit types are disabled `half` is a unique 32-bit float type with lesser promotion rank than `float`. Fixes llvm#81049
