Autosave/REST API: Block autosaving from overwriting changes when locked from editing.

Previously when a user was locked from editing a post in the block editor, autosave functionality was allowed to overwrite changes made by the editor that has taken control. This patch honors the lock status keeping autosave from conflicitng with other content editors.
