Clarify Tag Length Setting in OCB Mode

Fixes #8331: Updated the description for setting the tag length in OCB mode to remove the misleading “when encrypting” and “during encryption” phrasing. This change emphasizes that setting a custom tag length requires a call with NULL, applicable to both encryption and decryption contexts.

Clarify EVP_CipherUpdate() authenticated bytes behavior

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.

Amend the design of AlgorithmIdentifier parameter passing

I realised that any application that passes AlgorithmIdentifier parameters
to and from a provider may also be interested in the full AlgorithmIdentifier
of the implementation invocation.

Likewise, any application that wants to get the full AlgorithmIdentifier
from an implementation invocation may also want to pass AlgorithmIdentifier
parameters to that same implementation invocation.

These amendments should be useful to cover all intended uses of the legacy
ctrls for PKCS7 and CMS:

- EVP_PKEY_CTRL_PKCS7_ENCRYPT
- EVP_PKEY_CTRL_PKCS7_DECRYPT
- EVP_PKEY_CTRL_PKCS7_SIGN
- EVP_PKEY_CTRL_CMS_ENCRYPT
- EVP_PKEY_CTRL_CMS_DECRYPT
- EVP_PKEY_CTRL_CMS_SIGN

It should also cover a number of other cases that were previously implemented
through EVP_PKEY_ASN1_METHOD, as well as all sorts of other cases where the
application has had to assemble a X509_ALGOR on their own.

doc: improve documentation of EVP in-place encryption

The EVP interface explicitly allows in-place encryption/decryption,
but this fact is just 'partially' documented in `EVP_EncryptUpdate(3)`
(pun intended): the manual page mentions only operation failure in
case of 'partial' overlaps. This is not even correct, because
the check for partially overlapping buffers is only implemented
in legacy code paths.

Currently, in-place encryption/decryption is only documented for
RSA (`RSA_public_encrypt(3)`) and DES (`DES_ecb_encrypt(3)`), as
well as in the provider interface (`provider-cipher(7)`).

This commit amends `EVP_EncryptUpdate(3)` and `provider-cipher(7)`
to make the front-end and back-end documentation consistent.

ChaCha20-Poly1305 no longer supports truncated IV's.

Fixes #20084

In the 3.0 provider implementation the generic code that handles IV's
only allows a 12 byte IV. Older code intentionally added the ability for
the IV to be truncated.
As this truncation is unsafe, the documentation has been updated to
state that this in no longer allowed. The code has been updated to
produce an error when the iv length is set to any value other than 12.

NOTE: It appears that this additional padding may have originated from the code
which uses a 12 byte IV, that is then passed to CHACHA which zero pads it to 16 bytes.

Note that legacy behaviour in e_chacha20_poly1305.c has not been
updated.
