[aarch64] Add hyperbolic and arc trig intrinsic lowering (#98937)

## The change(s)
- `VecFuncs.def`: define intrinsic to  sleef/armpl mapping
- `LegalizerHelper.cpp`: add missing `fewerElementsVector` handling for
the new trig intrinsics
- `AArch64ISelLowering.cpp`: Add arch64 specializations for lowering
like neon instructions
- `AArch64LegalizerInfo.cpp`: Legalize the new trig intrinsics. aarch64
has specail legalization requirments in `AArch64LegalizerInfo.cpp`. If
we redirect the clang builtin without handling this we will break the
aarch64 compiler

## 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 is aarch64 needed
The last step is to redirect the `acos`, `asin`, `atan`, `cosh`, `sinh`,
and `tanh` to emit the intrinsic. We can't emit the intrinsic without
the intrinsics becoming legal for aarch64 in `AArch64LegalizerInfo.cpp`
