Combined Decrypt Calls
(This is a merge of http://go/wvgerrit/93829, http://go/wvgerrit/93830, http://go/wvgerrit/93832, http://go/wvgerrit/93833, and http://go/wvgerrit/93834 from the Widevine repo.) This implements the CDM code changes necessary to take advantage of Combined Decrypt Calls on OEMCrypto v16. The result of this is that WVCryptoPlugin is much lighter now because it can pass the full sample down to the core in one call, but CryptoSession is heavier, as it now has to handle more complex fallback logic when devices can't handle multiple subsamples at once. This patch also removes support for the 'cens' and 'cbc1' schema, which are being dropped in OEMCrypto v16. This fixes an overflow in the code for handling those schemas by removing it entirely. This patch also fixes the "in chunks" legacy decrypt path to use larger chunk sizes on devices with higher resource rating tiers.
