This PR builds GTK3 and GTK4 in parallel in order to add GTK4 build coverage.
I did attempt to do it in multiple stages with building the common portions first, but the supported way to do this had major performance issues using the actions/upload-artifact and actions/download-artifact GH Actions.
Putting the gvs-build directory in a tar was quick, but uploading took 15min. Compressing the directory using zstandard took greater than 30min, with similar long times with 7zip and gunzip. It looks like others have had these issues as well with actions/upload-artifact#199
I also removed pycairo and pygobject from the build pipeline because I don't think they are strictly necessary to test with the build now that installing them from PyPI is working.
Overall build time went down from 1hr to 34min with this change.
