util: When building 'ARM64EC', don't use x64 intrinsics which need to be emulated

Browse source 
ARM64EC is a new build target for Windows ARM64 devices for x64 support.
These binaries can be loaded in x64 processes, but don't need to be emulated. For
code that's heavily used, avoiding the emulation can be a huge perf win.
