  -----------
  [WebAssembly] Add intrinsics to wasm_simd128.h for all FP16 instructions (#106465)

Getting this to work required a few additional changes:
- Add builtins for any instructions that can't be done with plain C
currently.
- Add support for the saturating version of fp_to_<s,i>_I16x8. Other
vector sizes supported this already.
- Support bitcast of f16x8 to v128. Needed to return a __f16x8 as
v128_t.
