[gimp] app: port GimpDeviceManager and GimpDeviceInfo to GdkSeat

[Michael Natterer <mitch src gnome org>]

commit 89a4ea85ef5783f2eafde5529d26b86ccdd37cab
Author: Michael Natterer <mitch gimp org>
Date:   Wed May 16 19:54:58 2018 +0200

    app: port GimpDeviceManager and GimpDeviceInfo to GdkSeat
    
    and also be smarter about what devices we enable by default: enable
    all tablet devices and disable all things mouse, they can still be
    enabled in the device dialog.
