Adding chrome_inputs_per_frame.sql to track input count per frame This metric tracks the number of inputs per frame, as inputs get coalesced if the previous frame processing in the renderer hasn't finished yet, this is a good metric to track scroll jank as the more user input events per frame there is, the jankier the scroll. Bug:239406313 Change-Id: I0d77c8f4f399f9d6767b6d273e08cff9c4c61d51
