1654040 - Add some more information to the video frame profiler markers

Status: RESOLVED FIXED

(Core :: Graphics, task)

Description

[Markus Stange [:mstange]]

The youtube-playback raptor test seems to run out of frames in the compositor on macOS - the decoder isn't sending enough frames (or isn't sending the frames frequently enough) so the compositor has to pick old frames.
To confirm this, we can add a bit more information to the profiler markers.

Here's a profile that was collected by the raptor T-prof(ytp) job, with the new marker information: https://share.firefox.dev/3jm1Hpt
And indeed, all of the "Video frames dropped" markers are preceded by "0 remaining images" markers.
