Add UMA/Telemetry stats for touch event latency
This CL adds following UMA stats for touch event latency
1. Event.Latency.Browser.TouchUI:
touch event received by Chrome -> touch event sent to renderer
2. Event.Latency.Browser.TouchAcked
touch event sent to renderer -> touch event acked from renderer
Corresponding telemetry stats are also added.
BUG=chromium:246034
TEST=1. Check UMA stats exist in chrome://histograms/Event.Latency.Browser
2. Check the relevant stats are in telemetry smoothness test.
