[HLSL][clang] Add elementwise builtins for trig intrinsics (#95999)

This change is part of this proposal:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

This is part 3 of 4 PRs. It sets the ground work for using the
intrinsics in HLSL.

Add HLSL frontend apis for `acos`, `asin`, `atan`, `cosh`, `sinh`, and
`tanh`
