Cleanup: internal sequencer naming for overlays

- Rename RNA SpaceSeq.show_strip_overlay to show_overlays
  matching the 3D View, the term "strip" was misleading as this is used
  for the preview as well.

- Rename various RNA overlay settings to overlay_frame
  since "Frame Offset" is a specific feature, avoid having both
  Editor.show_overlay and SpaceSeq.show_overlays.

- Rename Editing `over_*` -> `overlay_frame_*` in DNA,
  as well as flags.
