Add an option to undo and redo motions

[godalming123]

I think that there should be an option to undo and redo motions/changes to the selection. This is similar to #12877, but more broad, since not only can you go back when you press <A-.> too many times, but you can also go back if you use any other wrong motions, which is especially useful for multi cursor, since it takes a couple keystrokes to re-setup your cursors in the right places if you accidentally use the wrong motion.
