Add latency metrics for recents gesture
Pass the touch down time to RecentsAnimation#startRecentsActivity.
Bug: 169221287
Test: Enable statsd log: "adb shell cmd stats print-logs"
Touch gesture navigation bar.
adb logcat | grep statsd | grep "(48)"
The line may contain 0x100000->4[I] 0x110000->20[I]
that means 4=by recents and 20=latency 20ms.
