Delete job item when corresponding entity is being deleted

Unfortunately this patch is adding code without explicit accessCheck(TRUE/FALSE) to content entity queries.

For example in the function "tmgmt_entity_delete" in the code file "tmgmt.module". This case is really worrying because it causes errors in the removal of any content, leaving Drupal 10 websites completely inoperative.

Added accessCheck() to the MR as it is a blocker when deleting any kind of entity, including configuration, so also causes deployment issues.

We might still decide whether or not we want this behaviour to become the default one (see #16).

Just adding diff from the MR to use with composer. The diff applies for 1.15 modules version, but has conflicts with the latest dev version.

Yes, this conflicts badly with another feature we added.

@berdir
what are the new features that conflicts with this patch?

Rebased with latest 8.x-1.x and fixed conflicts, had to rename tmgmt_update_8011 as tmgmt_update_8012
