Pass RawEvent latency from InputReader to InputListener

To keep track of the lower-level latency like touch driver latency, keep
track of the time when eventhub reads the events.

This information will be stored inside RawEvent as it is being read.

Next, this information will be passed to the InputListener. The InputListener will
report this data to LatencyTracker, which will aggregate this
information in order to get end-to-end touch latency.

Different mappers process the input_event events differently. So a
mapper-specific approach is used here.
