MCE Views: Add selection/deselection when a view is clicked.

These methods should be expanded to prevent content from being inserted into the view by blocking and rerouting keystrokes as appropriate as well as repositioning the caret before content is inserted.

see #21390, #21812, #21813, #21815.
