Figure out what's wrong with windows mingw 12

[danjenkins]

Github's runner image for windows now uses mingw 12... which causes us errors.

Look at #46 for more information.

Currently we're downgrading to mingw 11 but this action takes 12 minutes and isn't a cache-able thing...

Figure out what's up with using a later version of gcc/mingw on windows

Watch this issue - which explains that the version installed changes from msvc to UCRT actions/runner-images#8399

[danjenkins]

Reading the related links... it might be a case of changing setup-gstreamer to download the mingw version instead of msvc and that'll fix things, maybe

do you think we should maintain our own setup-gstreamer fork? Or would you rather fix this upstream?

[danjenkins]

I think we can make it an option in upstream - pass in an extra flag. Do a quick fork to see if it fixes the issue and if it does go and make it configurable so you can change which version gets installed; defaulting to msvc

moving over to the mingw build of gstreamer doesnt seem to have helped - https://github.com/go-gst/go-gst/actions/runs/6351376556/job/17253058164
