  -----------
  [WebAssembly] Add Support for Arc and Hyperbolic trig llvm intrinsics (#98755)

## Change:
- WebAssemblyRuntimeLibcallSignatures.cpp: Expose the RTLIB's for use by
WASM
-  Add trig specific test cases

## History
This change is part of an implementation of
https://github.com/llvm/llvm-project/issues/87367's investigation on
supporting IEEE math operations as intrinsics.
Which was discussed in this RFC:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

This change adds wasm lowering cases for `acos`, `asin`, `atan`, `cosh`,
`sinh`, and `tanh`.

## Why Web Assembly?
>From past changes to try and support constraint intrinsics the changes
to the trig builtins to emit intrinsics\constraint intrinsics broke the
WASM build. This is an attempt to preempt any such build break.
