Fix T91237: Wrong Editors could sync animation 'Visible Range'

This was reported for the Outliner.

It was possible to set 'show_locked_time' on any space (via python, not
sure if there are other ways to achieve this).
Navigating in an animation editor obviously ruined the layout in certain
Editors that are not made for this.

Now restrict syncing to editors that support it well (the ones that have
this setting exposed in their menus) and prevent setting this in RNA.
