UI: top-bar reorganization

This hides the top-bar by default for everything
besides paint/sculpt workspaces.

- Use the top-bar mainly for active tool settings &
  popovers panel options.
  (transform / snap settings are an exception for this convention).
- Only show the top-bar (by default)
  in paint work-spaces (sculpt / texture-paint / grease-pencil).
- Add an active-tool panel to the sidebar.
- Split 3D view tabs into (Item / Tool / View).

D4721 with minor changes.

Further work is needed for the top-bar and image-editor.
