ci: Remove lava-job-submitter, LAVA containers, and tests

lava-job-submitter has been moved to a new repository:
https://gitlab.freedesktop.org/gfx-ci/lava-job-submitter

Remove the LAVA-related code from Mesa, since we now use the containers
built in that repository. These containers already include
lava-job-submitter and run the relevant tests there.
