(This is a merge of http://go/wvgerrit/51084) Nominally, OEMCrypto probably shouldn't modify the buffer descriptor we pass into OEMCrypto_DecryptCENC(), but in practice, we know some platforms do this, so we make defensive copies in CryptoSession::DecryptInChunks() just in case. Turns out, some devices also behave like this in OEMCrypto_CopyBuffer(), so we should also be doing defensive copies in CryptoSession::CopyBufferInChunks().
