scripts: add build-matrix script to ease matching ci

[trws]

problem: we have good scripts for running in our images locally, but not always with all the same flags as in CI

solution: add a script, build-matrix, that takes a name from the actions build matrix and runs docker_run_checks with the same flags as that matrix entry

Great idea! I like that the script can also list the entries in the matrix.

Thanks both of you, cleaned up a little bit and added it to the list to be processed by pre-commit so the style checks run on it.
