Add recently published media registries and notes (#1425)

This adds the registries and notes recently published by the Media WG.

Tested with `npx browser-specs build`. Note the need to set the series
shortname for `eme-stream-mp4` otherwise the code would strip the `4`.

This revealed a couple of places where the W3C API returned incorrect
information. Now fixed.

I also took the opportunity to drop series titles that had been set because the
W3C API also returned incorrect information, and that are no longer needed.
