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.
