Tag object/scene for selection update from operators

Before that depsgraph tagging was done from inside notifier listener in
viewport. This had the following issues:

- If there are no viewports, selection tag was not done. Causing possible
  issues when object becomes visible.

- Required special trickery to detect which data to tag for update.

- Was causing crash when transforming/selecting markers in clip editor.
  This is because selecting marker needed to poke viewport to redraw, since
  selected bundles will be displayed differently in viewport.
