UI: allow to hide markers region per editor

Instead of having the option to show marker lines,
make the marker region optional.

- Added a Show Markers entry in the View menu of the animation editors.
- If the markers region is not active then the Marker menu gets hidden.
- Removed marker menu from the driver editor
  and don't allow to use marker operators.
