This commit is a work forward having less updates during playback, which speeds things up a lot here. The idea is simple: stop update all copy-on-write datablocks (which implies full re-evaluation actually) on frame change and re-use existing evaluated meshes as much as possible. This brings playback speed to 24 fps on the dino test scene here. Performance drops down a lot when armature is animated tho, but that's because of need of tangent space calculation which we can't do much about from just a dependency graph. Hopefully this doesn't make copy-on-write too unstable, quick tests here are surviving fine.
