Add __hlt, which is a MSVC ARM64 intrinsic. This intrinsic is just the HLT instruction. MSVC's version seems to return something undefined; in this patch it will just return zero. MSVC intrinsics are defined here https://learn.microsoft.com/en-us/cpp/intrinsics/arm64-intrinsics. I used unsigned int as the return type, because that is what the MSVC intrin.h header uses, even though it conflicts with the documentation.
