sna/present: Try exchanging the Pixmap with a scanout-ready bo

Try to avoid more clflushing on the current Pixmap if we have a scanout-ready bo in the cache. We also note that since we unflip before any other drawing takes place, we do not need to mark the flipped Pixmap as being pinned to the scanout.
