ci: Run desktop GL 3.0, 3.1, 3.2 tests
Support and run desktop GL 3.0, 3.1 and 3.2 tests in CI.
Additional GL 3.x and 4.x tests may be added once our dEQP runner tool gains support for them.
On GLES hosts softpipe does not support GL_{OES|EXT}_texture_buffer, and thus cannot advertise GL 3.1 and beyond, which causes all relevant tests to fail with BadTerminate.
