Add Support for WebM Back

Browse Source 
Adds support for WebM to the CDM. Decryption remains untouched,
however the initialization data is passed differently for WebM.

The previous version of this change broke playback for certain
apps that were being allowed to pass invalid MIME types before
this change was made. This version maintains backwards-compatiblity
for these apps for now by rewriting their MIME types as "video/mp4".

Merge of https://widevine-internal-review.googlesource.com/9225/
and https://widevine-internal-review.googlesource.com/9611/ from
the Widevine cdm repo.
