Make sure INPUT_EVENT_LATENCY_BEGIN_RWH_COMPONENT is created when event passes through RWHI
We want every input event to have a INPUT_EVENT_LATENCY_BEGIN_RWH_COMPONENT
in its LatencyInfo as the starting point for measuring input latency. In some
test cases the synthetic mouse/mouse wheel event can miss the component:
For example, for non-aura platform,
SyntheticGestureTargetBase::DispatchWebMouseWheelEventToPlatform calls
RWHI::ForwardWheelEventWithLatencyInfo(), while we only enforcing creating
the begin component in RWHI::ForwardWheelEvent().
The fix in this CL is to move CreateRWHLatencyInfoIfNotExist() call, which
enforces that the begin component exists/is created in the LatencyInfo, from
RWHI::ForwardWheelEvent into RWHI::ForwardWheelEventWithLatencyInfo.
The same is applied to FowardMouseEvent(WithLatencyInfo)().
BUG=246034
TEST=run telemtry smoothness test agasint non-aura linux build, and make sure
that INPUT_EVENT_LATENCY_BEGIN_RWH_COMPONENT exists for mouse wheel event's
LatencyInfo.
