 	 * Pre-populate the cache of canEdit, canView, canDelete, canPublish permissions.
Add a deprecation-friendly version of the prepopulate_permission_cache function

Add a function with the old function name that adds a deprecation warning for
users but forwards the call to the renamed function for backwards-compatibility.
