Level Sequences now use UOLs for their bindings. Level Sequence player context is now an ALevelSequenceActor if possible. All bindings (including the extreme-legacy lazy object ptr bindings) are now upgraded to use the UOL binding mechanism. Introduced a new concept for reasoning about object hierarchies in Sequencer: object schemas. Schemas allow customization of how Sequencer handles finding 'parent' and 'child' objects, which allows us to genericize lots of the hard-coded Actor-Component logic. This is just a first pass - there are still many places that directly deal with AActor and UActorComponent, which will be gradually migrated with upcoming work. #jira UE-199305 #rb david.bromberg, ludovic.chabant [CL 29932924 by andrew rodham in ue5-main branch]
