[Cocoa] visualize-media-element-timeline: a utility to convert log entries to
an interactive representation of a media element timeline

Reviewed by Eric Carlson.
Add a utility to visualize the output of (e.g.) `log stream` to correlate
HTMLMediaElement and MediaPlayerPrivate events and place those
events onto an interactive timeline.
The utility reads logs in ndjson format, and uses those logs to emit HTML. The
basic view includes a row for each media element identifier
appearing in the logs, with color coded play durations. ReadyState and
NetworkState durations are available as a detail of each row. Notable
events are overlayed atop the media element's timeline, and details are visible
on hover.
* Tools/Scripts/visualize-media-element-timeline: Added.
