Shift TouchEventAcking to TEAQ

This CL makes TouchEventAckQueue responsible for calling
ProcessAckedTouchEvents() on the root view. Several main changes:

1) The TEAQ now stores the full TouchEvent, not just the event's
touch ID. This is required by ProcessAckedTouchEvents().

2) With the assumed invariant that now all touch events are
acked, and in-order, we don't need to explicitly mark emulated
touch events as such, since we can use the TouchEmulator to keep
track for us.

3) The TEAQ now holds a pointer to its owning RWHIER, since it
needs access to both (i) the TouchEmulator, and (ii) the function
IsViewInMap(). The latter means having to make IsViewInMap() a
public function on RWHIER.
