Previously JS would split the auth tag from the ciphertext before passing both to the *Job for AEAD decryption. Now the full data is passed to C++, which handles the split and validation internally.
Applies to AES-GCM, AES-OCB, and ChaCha20-Poly1305.
This also fixes an edge case where if
ciphertextis, or is backed by, a detached arraybuffer the spec tells us to treat it as an empty byte sequence. Before we would TypeError on trying to slice it, now we correctly OperationError after C++ handles the ByteSource copy per spec.
