This change updates the ChaCha20-Poly1305 AEAD to be able to process
|extra_in| data. It does this by encrypting the extra data byte-by-byte
(because extra data should be very small). Both the generic and assembly
code is updated to be able to include this extra ciphertext in the
Poly1305 calculation.

These behave like EVP_AEAD_CTX_{seal,open} respectively, but receive
ciphertext and authentication tag as separate arguments, rather than one
contiguous out or in buffer.

In order to use AES-GCM-SIV in the open-source QUIC boxer, it needs to
be moved out from OPENSSL_SMALL. (Hopefully the linker can still discard
it in the vast majority of cases.)
Additionally, the input to the key schedule function comes from outside
and may not be aligned, thus we need to use unaligned instructions to
read it.
