[media-source] Clarify codec name for isTypeSupported/addSourceBuffer interop of FLAC-in-MP4

wolenetz has just created a new issue for https://github.com/w3c/media-source:

== Clarify codec name for isTypeSupported/addSourceBuffer interop of FLAC-in-MP4 ==
Support by MSE for FLAC in MP4 is becoming more commonly requested (FF has it supported as of 51, Chrome is looking into supporting it in M62 -- https://crbug.com/666000).

Inspecting RFC 6381, it is unclear to me on first read what the "codecs" string should contain to interoperably ask about support for FLAC-in-mp4 because the MP4RA codecs listing (http://www.mp4ra.org/codecs.html) doesn't explicitly list FLAC.

This issue is to track discussion and obtaining agreement on interop for which codec string to support for indicating FLAC-in-MP4 support.

@jyavenard, is it simply 'audio/mp4; codecs="flac"' or 'video/mp4; codecs="flac"' (possibly along with other codecs for the other codecs in the stream)?
