Fix T85974: Edit-mode undo/redo causes assertion

Without legacy-undo, loading memfile undo only cleared edit-mode data
for mesh and armature object types.
This causes an assertion when loading edit-mode undo steps afterwards
for other object types as the existence of this data made entering
object mode fail.

Resolve this by freeing all objects types undo data from ED_editors_exit
