This is a follow-up to #128363, and fixes up the remaining areas of the sequencer's code that didn't yet account for slotted actions: 1. Moving strips failed to move their animation with them. 2. Duplicating strips failed to duplicate their animation with them. 3. Deleting strips didn't delete their animation channels with them. This also takes the opportunity to add depsgraph tagging and notifiers that were already missing in the pre-slotted-actions code, for the strip delete and strip paste operators. The absence of these was making the UI not update and was also causing stale animation data to get evaluated. Pull Request: https://projects.blender.org/blender/blender/pulls/128440
