Reland r262568 "Encrypted Media: Check container mime type in MediaDrmBridge".

This CL relands r262568 with NO additional changes. The original CL was reverted to help investigate some test failure, which turned out to be unrelated to this CL.

Android MediaDrm API supports container mime type check in
isCryptoSchemeSupported (UUID uuid, String mimeType):

http://developer.android.com/reference/android/media/MediaDrm.html#isCryptoSchemeSupported(java.util.UUID, java.lang.String)

This CL hook this API up in MediaDrmBridge.

Also, Chromium will always query the codec/container type it
is interested in (e.g. MP4 and WebM).
