Re-land: Refactor Select-to-speak so that mouse events are forwarded to the extension.

Originally landed: r472339 (https://codereview.chromium.org/2814213002)
Reverted: r472397 (https://codereview.chromium.org/2883283003)

Previously the Select-to-speak event handler captured mouse events and
turned them into accessibility events that could be caught by
select-to-speak.

Instead, the event handler can mouse and keyboard events to the extension
background page, and the extension can use the automation API to do a hit test.

This is mostly a refactoring change, but it gives us some more flexibility
and makes the event handler simpler, possibly something that could be
general-purpose, while putting more of the logic into the extension code.
