mingw: Exclude utf8 manifest [PR111170, PR108865]

Make the utf8 manifest optional (on by default and
explicitly off with --disable-win32-utf8-manifest)
in the mingw hosts.

Also eliminate duplication between the 32-bit and
64-bit mingw hosts by putting them both in the
same branch and special-case only the 64-bit long
long setting.
