[RFC PATCH] gitlab-ci: Test compilation on Windows with MSYS2

[Thomas Huth]

Gitlab also provides runners with Windows, we can use them to
test compilation with MSYS2.

However, it takes quite a long time to set up the VM, so to
stay in the 1h time frame, we can only compile and check one
target here. And there is also still a problem with compiling
the multiboot.bin in pc-bios/optionrom/, so this is currently
disabled, too.

 I'm sending this out as an RFC in case somebody else wants to play
 with this. Considering that the corresponding job in Cirrus-CI compiles
 way more targets within 1 hour, we might rather want to keep using
 the Cirrus-CI job instead?
