File util, generic crypto, and key query

This CL merges several CLs from the widevine repo:

http://go/wvgerrit/18012 Add support for querying allowed usage for key.
http://go/wvgerrit/17971 Add per-origin storage.
http://go/wvgerrit/18152 Add OEMCrypto's generic crypto operations to CDM.
http://go/wvgerrit/17911 QueryKeyControlInfo => QueryOemCryptoSessionId

Note: numbering in wv_cdm_types.h was added in this CL and will be
back ported to wvgerrit in a future CL.
