[DirectX] Add emulation for fp16 types of llvm.is.fpclass (#157505)

fixes #157504

This changes adds the emulation we need for IsNaN, IsNormal, & IsFinite
This change only applies these emulations to the llvm.is.fpclass cases
of fp16.

Since there is no DX intrinsics yet for these cases, applying the
emulation to the necessary intrinsics is left for future implementers of
