  [clang][ARM][AArch64] Reapply "Define intrinsics guarded by __has_builtin on all platforms (#128222)" (#140910)

The original change caused issues on MSVC due to a new warning thrown
inside MSVC headers. That was fixed
[here](https://github.com/llvm/llvm-project/pull/142019), so reapply
this commit. Original description below.

Instead of defining ARM ACLE intrinsics only on MSVC and guarding
wrapper functions in headers with __has_builtin, universally define the
intrinsics as target header builtins.
