Pass ProductId+VendorId+Source info to LatencyTracker
Currently InputEventLatencySketch captures the aggregated latency over
all devices, and it doesn't capture per-device latency.
In order to capture latency metrics per device, we track the timeline
for latency information for each Product Id, Vendor Id and Source
individually.
