[mutter/wip/carlosg/input-refactors-pt1: 23/32] backends/native: Drop all uses of clutter_input_device_get_stage()

[verdre <jonasd src gnome org>]

commit 88c736f31bceddcf11b68943c9556a2ec2778def
Author: Carlos Garnacho <carlosg gnome org>
Date:   Fri Jun 5 16:52:10 2020 +0200

    backends/native: Drop all uses of clutter_input_device_get_stage()
    
    Rely on the seat stage, or other ways to fetch it. Also rely that
    there is actually a single stage, so that we assign the right stage
    to all events going out of the seat, in a single place.
