gitlab-ci: Test compilation on Windows with MSYS2

Gitlab also provides runners with Windows, we can use them to
test compilation with MSYS2, in both, 64-bit and 32-bit.

However, it takes quite a long time to set up the VM, so to stay
in a reasonable time frame, we can only compile and check one
target here.
