[HLSL] Remove Double from pow intrinsic

[farzonl]

We don't have double pow intrinsics in dxc:
https://godbolt.org/z/P4c8dKvcG

code to be removed:
https://github.com/llvm/llvm-project/blob/main/clang/lib/Headers/hlsl/hlsl_intrinsics.h#L1177C1-L1184C31

The change will also need to remove the accompanying tests.
