Fixes#8310: Document that the number of authenticated bytes returned by EVP_CipherUpdate() varies with the cipher used. Mention that stream ciphers like ChaCha20 can handle 1 byte at a time, while OCB mode requires processing data one block at a time. Ensure it's clear that passing unpadded data in one call is safe.

Previously the documentation for `SSL_CIPHER_description` said:
> If buf is provided, it must be at least 128 bytes, otherwise a buffer
> will be allocated using OPENSSL_malloc().
In reality, `OPENSSL_malloc` is only invoked if the provided `buf`
argument is `NULL`. If the `buf` arg is not `NULL`, but smaller than
128 bytes, the function returns `NULL` without attempting to allocate
a new buffer for the description.
This commit adjusts the documentation to better describe the implemented
behaviour.

Fixes#23075
In OpenSSL 3.2 EVP_DigestSign and EVP_DigestVerify
were changed so that a flag is set once these functions
do a one-shot sign or verify operation. This PR updates the
documentation to match the behaviour.
Investigations showed that prior to 3.2 different key
type behaved differently if multiple calls were done.
By accident X25519 and X448 would produce the same signature,
but ECDSA and RSA remembered the digest state between calls,
so the signature was different when multiple calls were done.
Because of this undefined behaviour something needed to be done,
so keeping the 'only allow it to be called once' behaviour
seems a reasonable approach.
