compositor: Configurable behavior when window to be focused conflicts with fullscreen (#12033)

Renames `misc:new_window_takes_over_fullscreen` into
`misc:on_focus_under_fullscreen` and implements the following behavior:

- By default, when a tiling window is being focused on a workspace where
  a fullscreen/maximized window exists, respect
  the `misc:on_focus_under_fullscreen` config variable.
