Draft: r300/ci: add dEQP job with RADEON_DEBUG=notcl
This is a draft currently, still need to figure out why so many tests fail in CI which pass locally.
r300/ci: add dEQP job with RADEON_DEBUG=notcl
This forces software vertex processing via the draw module and should hopefully test the exact same codepaths that the r300 chipsets without built-in vertex engines use.
