app: add gimp_drawable_update_all()

Browse source 
Add a new GimpDrawable::update_all() virtual function, and a
corresponding gimp_drawable_update_all() function, which updates
the full contents of the drawable.  Unlike calling
`gimp_drawable_update (drawable, 0, 0, -1, -1)`, which updates the
entire drawable area, gimp_drawable_update_all() only updates the
area that has actual content.  While the default implentation does
simply update the entire drawable area, GimpGroupLayer overrides
this function to recursively update its child layers, rather than
the its entire area.
