Summary MachSendRights can release their IOSurface use-counts before CA adds a new ones

CoreAnimation doesn't add a new use-count to CAIOSurfaces until the transaction is committed, which is after the MachSendRight (inside LayerTreeTransaction/RemoteLayerBackingStoreProperties) is destroyed. We should run an explicit CATransaction for layer tree commits to ensure that we always have a use-count added.
