Subject: Animation: Add redo panel to Dopesheet and NLA

Add the Redo panel to the dopesheet & NLA editors. This also implicitly
adds it to the timeline editor, since it's a kind of action editor
internally.

This feature is needed for changing advanced properties of animation
operators, such as select grouped (see D14811). But it can also be
useful for existing operators, like precise keyframe position tweaking.

Changes are basically the same as in D6286 (which added the redo panel
for Graph Editor).

Some operators have internal properties that should be hidden. A full
list can be found in T98195. These will be fixed in a follow-up patch.
