[SQUASH ON REBASE] Remove Windows ARM BaseTools Build

The Windows ARM BaseTools build is not used any longer, it used
to work on Windows ARM64, but that support is not there anymore.
Windows ARM64 is built for BaseTools instead and there are no
current Windows ARM hosts, nor likely ever to be any more.

This can be squashed with the original commit adding CI (or the
commit adding these BaseTool builds, if separate).
