Handle ARM64EC as ARM64.

Browse Source 
ARM64EC is a new ARM64 variant introduced in Windows 11 that uses an
ABI similar to AMD64, which allows for better interoperability with
emulated AMD64 applications. When enabled in MSVC, it defines _M_AMD64
and _M_ARM64EC, but not _M_ARM64, so we need to check for _M_ARM64EC.
