[ci] Move pregen steps into a composite action (wpilibsuite#7474)

This ensures that complete uniformity in how the generation scripts are run. All dependencies and scripts are set up in the exact same way, each time. The old pregen_all script has been removed and moved into the composite action to ensure failed scripts will always fail the job.
