mojo events: Add |screen_location| to located events.
Building blink events requires more data than we currently pass through
mojo::EventPtr. That data is available on the side that has the
base::NativeEvent, so we now send both the view relative location and
the system location through. This also lets us drop a DEPS on "ui/events"
from the html viewer.
Eventually, we'll want our own event types, but this works for now.
