LYN-1818 | [USE CASE] Reparenting between different prefab instances by drag/drop in the Outliner (#1088)

* Add the last known parent to the prefab undo cache to detect changes in the owning instance.
Still WIP.

* Progress in handling reparenting. Still WIP, need a change in CreateLink that will be addressed in a separate branch and then merged back.

* A few fixes, reparenting now works with entities. Still working on instances.

* Fix assert crashing the Editor because of the arguments being in the wrong order.

* Handle moving the patches when removing and recreating links when reparenting nested instances.

* Rearrange some code to prevent including instance removal in instance update undo node, as it would be redundant and cause errors in some edge cases.

* Reorder instance reparenting to account for correct order of operation during undo/redo

* Fix order of operations to support multiple operations in one edit (reparenting to non-container entities while changing instance)

* Add function to refresh patches on links to allow aliases to be restored correctly on reparenting.

* Removed RefreshEntityPatchOnLink function. Introduced a simpler way of handling porting patches.

* Removing unnecessary code that was left after testing.

* Minor fixes to naming and comments.

* Restore previous error, no longer printing the failed patch.

* Remove unused includes.

* Restore include removed by mistake.

* Simplified patches retrieval by using internal function. Renamed some internal functions and variables to be more accurate.
