gdk/frameclock: Make surfaces inhibit freeze To make a frame clock tick as long as any of the associated surfaces expect to receive ticks, make the surfaces inhibit freezing the clock, instead of directly tell the frame clock to freeze itself. This makes it so that as long as any surface using a certain frame clock is not frozen (e.g. just received a frame event from the display server), the frame clock will not be frozen. With this, the frame clock is initiated as frozen, and won't be thawed until any surface inhibits freeze. It will be frozen again, when every surface has that previously inhibited freeze uninhibited freeze.

surface: Add an autohide property This api is meant to mimic xdg-popover.grab - we show the surface, and dismiss it when we get events on other surfaces. For foreign surfaces, the compositor handles that for us; for our own, we check outselves before delivering events to GTK.

Get rid of GdkSurfaceImpl We don't need the complicated wrapper system anymore, since client-side windows are gone. This commit moves all the vfuncs to GtkSurfaceClass, and changes the backends to just derive their surface implementation from GdkSurface.

gdk/surface: Add toplevel_resize vfunc To separate how toplevels and popups are configured, a first step is to introduce a resize-only vfunc for backends to implement. It's meant to only configure toplevel windows, i.e. popups. Currently it's used for both types, but introducing the resize-only API is a first step.
