In order to make things more and more asynchronus and to each time we paint be an isolated event, that can be potentially be applied individually or together with other updates, make it so that each time we draw, we use the transient MetaFrameNative (ClutterFrame) instance to carry a KMS update for us. For this to work, we also need to restructure how we apply mode sets. Previously we'd amend the same KMS update each frame during mode set, then after the last CRTC was composited, we'd apply the update that contained updates for all CRTC. Now each CRTC has its own KMS update, and instead we put them in a per device table, and whenever we finished painting, we'll merge the new update into any existing one, and then finally once all CRTCs have been composited, we'll apply an update that contains all the mode sets for all relevant CRTCs on a device.
