Overhaul Mandoline event transport code
In the course of its development, Mandoline's event code has diverged away
from event payloads that are a good fit with the current state of blink's
input handling logic. This CL begins a process of updating the event code
with an extended wheel interface capable of supporting the standards track
wheel event and revised pointer events that will be extended in a future
CL with support for the pointer events specification.
