tf-m-lava-submit, etc.: Add DEVICE_FILTER parameter

This is intended to be an optional switch to pass to lava_submit_jobs.py
script: --fvp-only or --physical-board-only, to limit submitted LAVA
tests to FVP devices only, or vice-versa, to physical devices only.

This is helpful during development and debugging, and maybe useful to
optimize some production jobs.
