Summary Web Inspector: show wall time frame duration on the vertical overview

We'd like to spot frames that took long to render even in cases where CPU time usage by nested events was small, so add a contour for overall frame length to frame bars in the vertical overview. This also requires better scaling logic, so that should we have any irregularly-long frames (i.e. in absence of requestAnimationFrame calls), these do not dwarf the rest of the frames -- so we now scale to no more than 3 * median_frame_length, which causes badly outlying frames to rocket into the sky (right in time for April, 12th).
