Draw the start of input latency using its original/ui timestamp
Currently we draw the start of input event's latencyinfo using the
timestamp when we issue the async trace event when the input event
is passing through RWH. This CL changes that we now draw the start
of input event's latencyinfo using the input event's orignial/ui
component's timestamp so visually we can better see when the input
event was created.
BUG=396236
TEST=do scroll latency tracing on pixel/android, see that now latency
for TouchMove and GestureScrollUpdate are drawn at the same starting
time.
