lima maintains a context manager per drm_file, similar to amdgpu. In order to account for the complete usage per drm_file, all of the associated contexts need to be considered. Previously released contexts also need to be accounted for but their drm_sched_entity info is gone once they get released, so account for it in the ctx_mgr.
