[CRT] ARM & ARM64 Windows do not have initenv in their CRTs (#1597)

Browse source 
Native CRT on ARM & ARM64 Windows doesn't have these functions.
For compatibility, it's mandatory to not have it at all. Otherwise,
ARM executables built for ReactOS do not run on true ARM Windows.

Consider doing full sync with mingw-w64 CRT in future.
