Add cipher mode and pattern encryption support

Browse Source 
[ Merge of http://go/wvgerrit/16364 ]

http://go/wvgerrit/16249 changed the name of the encryption pattern
structure from OEMCrypto_PatternDesc to OEMCrypto_CENCEncryptPatternDesc
to remove ambiguity. These are matching changes to CDM core.

[ Merge of http://go/wvgerrit/16340 ]

This CL passes the cipher mode in the license to OEMCrypto when
keys are loaded and specifies the pattern encryption scheme to
OEMCrypto_DecryptCENC.
