Add quirks to emulate undo and redo in hidden editable areas on some websites
https://bugs.webkit.org/show_bug.cgi?id=197452

Reviewed by Alex Christensen.

Source/WebCore:

UI change, not testable.

We need to send synthetic keyboard events to the web process to emulate undo and redo
key combinations for when we are trying to get our undo and redo UI to work
on rich editing websites that only listen to keystrokes, and don't let us use our
undo manager to help manage the input content.

Source/WebKit:

We need to make our own undo manager to allow undo even when
the manager is empty. This is to interface with rich editing
websites that don't actually interface with our undo abilities.
Then we need to generate synthetic undo and redo in the web process.
