Speedup CI by merging checkers with matrix

1. This reduces the number of parallel jobs, removing time waiting for additional runners, removing the time that the very long build jobs are just waiting and doing nothing.
2. Spending less time setting up and installing in these checkers jobs

Each step will still print out its errors. Checkers are still kept separate from build jobs to not "leak" anything into them or make them any longer.

Also used the new allow-prereleases to simplify the python-version matrix.
