Build Windows ARM wheels

This can be done on GH Actions using the new windows-11-arm runners, see e.g.

I think when I added manylinux ARM wheels it was not yet possible to use Windows ARM runners. It might be as easy as gh-259 now but I can imagine that there might be more problems in the Windows case. For a start I don't know how well msys handles Windows on ARM.

I tried to use this recipe in aleaxit/gmpy#582, but without luck: the GMP build fails (with msystem=clangarm64 and mingw-w64-clang-aarch64-gcc).

Though, maybe ucrt64 build will work for the python-flint, as it doesn't use MVSC.

@skirpichev Based on your experiments in aleaxit/gmpy#582, with some modifications, I was able to build GMP/MPFR/MPC in passagemath/passagemath#1194
