[tp] Add range of interest feature for track events - Introduces a new TracePacket type for specifying the "range of interest" - Introduces a new trace processor flag for enabling track events cropping based on this new packet, disabled by default - Updates the chrome_reliable_range.sql metric to rely on this packet when it's present in the trace (computing the reliable range on an already cropped trace may produce incorrect results) Bug: b/239830951 Change-Id: Ieea9c2bb3c90dde4325033864153093afe3a300c
