Subject: BaseTools: Adding support of building BaseTool on Windows ARM/ARM64

This change focuses on the support of building basetool natively for
Windows ARM/ARM64 host system, which will enable the ARM based platforms
to build UEFI and unit tests.

Note that the warnings due to integer conversions are suppressed for
this specific target to avoid too much local changes carried in MU. The
formal change should drop all these binaries and move to pythonic
scripts.

The binary output is tested on Windows ARM based hardware systems.
