drm/ci: fix merge request rules

Merge request pipelines were only created when changes
were made to drivers/gpu/drm/ci/, causing MRs that
didn't touch this path to break. Fix MR pipeline rules
to trigger jobs for all changes.

Run jobs automatically for marge-bot and scheduled
pipelines, but in all other cases run manually. Also
remove CI_PROJECT_NAMESPACE checks specific to mesa.
