The EME spec technically requires CDMs to treat audio/mp4 and video/mp4 equivalently, as well as audio/webm and video/webm. We had only been accepting video/mp4 and video/webm up until now. This change also centralizes handling of init data types in the shared CDM code instead of having it spread across multiple places in the codebase. (This is a merge of https://widevine-internal-review.googlesource.com/9532/ from the Widevine CDM repo.) Bug: 13564917 Change-Id: Ib8bdfb2b003ffb00e8f0559561335abb3c5778b0
