This will allow identifying Windows Visual Studio targets as aarch64;
the Microsoft compiler does not define __aarch64__.
An alternative would be to define this in the code, checking for
_M_ARM64 or _M_ARM64EC. For now we'll use the existing VPX_ARCH_*
system. For compatibility VPX_ARCH_ARM will continue to be defined to 1
in this case.
