Send consumeTime from the app to InputDispatcher

When the app completes an input event by calling 'finishInputEvent', it
will now notify InputDispatcher about the time when the event was first
read by the app.

This will help InputManager collect dispatching latency statistics.

Sample dumpsys output for validation:
    android.view.ViewRootImpl$WindowInputEventReceiver
       mInputChannel: da2dbc7 com.google.latencyTester/com.google.latencyTester.activities.MainActivity (client)
       mSeqMap: {}
       mReceiverPtr:
        mInputConsumer:
          mResampleTouch = true
          mChannel = da2dbc7 com.google.latencyTester/com.google.latencyTester.activities.MainActivity (client)
          mMsgDeferred: false
          Batches:
              Batch:
                  Message 2277: MOTION action=MOVE
                      Pointer 0 : x=643.0 y=961.0
          mSeqChains:
              <empty>
          mConsumeTimes:
              seq = 2277 consumeTime = 74385633441431
The above dump was acquired during touch of the latencyTester app.
Also verified that normally, mConsumeTimes is empty.
