Move LatencyStatistics collection from InputReader to InputTransport
This move allows us to grab a bigger context of how much time a motion
event is spent from the kernel to right before the event was published.
Test: Modified LatencyStats to report ever 10 seconds. Utilized logs to
check that logs were reporting every 10 seconds. Checked also using
logs that data was being added and calculated correctly.
