aura: Gesture event plumbing (skeleton).

Add gesture event plumbing through aura. This is not functional just yet.
Subsequent CLs will move the gesture-recognizer from views into aura,
which will then generate and deliver aura gesture events.

BUG=11024
TEST=no functional changes yet. Tests will be added when GR is moved into aura.
