freedreno: add CI for envytools tools

This also tunes `.freedreno-rules` a bit so that it isn't triggered by
various tools that don't effect the driver build.

The .gitlab-ci directory is kept separate from the toplevel one so that
updates to (for example) reference decode output do not trigger all the
other-driver jobs to run.
