Added support for MSVC ARM64EC target.

Browse Source 
ARM64EC is similar to ARM64 in that the binary will run natively on
ARM64 CPUs and therefore supports all ARM64 intrinsics. The difference
is that it also supports AMD64 intrinsics (and therefore defines _M_AMD64
and _M_X64), which will be emulated by an implicitly linked library.
ARM64EC also changes ABI compared to ARM64, but it doesn't affect
Boost.Atomic.

Changed predefined macro checks in order to use msvc_arm backend for
ARM64EC instead of msvc_x86. The benefit is that msvc_arm uses memory
order-aware intrinsics instead of the full-fence ones on x86. The
downside is that 128-bit atomics won't be available (for now).

Also define BOOST_ATOMIC_DETAIL_INT_FP_ENDIAN_MATCH for ARM/ARM64
on Windows.
