about:media-internals page should show MSE events

Project Member Reported by fbeaufort@chromium.org, Aug 18 2017

Issue description

It would be nice to see and filter all MSE related events in internal about:media-internals.

Here'a a list to start with of new MSE properties :
- mse_sourceopen
- mse_sourceended
- mse_sourceclose
- mse_updatestart
- mse_update
- mse_updateend
- mse_error
- mse_abort

Interesting idea. We'd probably want to make such logging opt-in to prevent spamming the logs.

I chatted with Dan and we wonder if something like EME logger (https://developers.google.com/web/updates/2015/09/eme-logger) (but for MSE) would be a good alternative (or complementary) approach (though such wouldn't immediately work on Android, but Dan had some ideas for follow-on approaches that might help there).

An MSE logger extension could go a long ways to help developers, but it wouldn't interleave events in the rest of the media-internals logs. Nor would it have the benefit of differentiating possible event logs like "queued updateend" versus "dispatched updateend to JS app". Perhaps both an extension plus extra media-internals logging?? Or maybe Dan's follow-on approaches might afford a good hybrid.

An opt-in checkbox in about:media-internals would be my favorite choice.
