[Lens] Support undo/redo

[wylieconlon]

There are various techniques that could be used to support undo/redo in Lens, but most will depend on a core restructing: #52792 One of the main features of the restructuring is to put all state into the top level, which would be useful for tracking undo/redo history.

Undo/redo systems can be tricky. Most Kibana apps sync their state to the URL, which gives a nice integration with the browser forward/back buttons. But Lens does not currently save its state to the URL, and the Lens state is a large object that should only get partially serialized.

The simplest undo/redo system for Lens would be to store the previous N state objects in their entirety. To "undo," we go back to the previous state. Every time the state changes, clear the "redo" list. This would be limited but effective.
