ci/windows: Revert to using GCC for MinGW builds

Using MinGW in the future may not be ideal as it does not work very well
with crash dumps (#8682).

Switch back to GCC on MinGW. This also gives CI a way to check GCC 12
(as of writing, or whatever version of mingw-gcc Arch happens to be
shipping on a given week).

[video_core] Update 3D registers

fsp_srv: stub GetCacheStorageSize

vk_scheduler: wait for command processing to complete

cmake: Fix FindPkgConfig

The graphics API setting should not be changed when a game is running.
