Encrypted Data does not support AEAD algorithms. If you wish to
use AEAD algorithms you will have to use a CMS_AuthEnvelopedData
structure. Therefore, when AEAD algorithms are used with
CMS_EncryptedData_set1_key will now return an error.

Add the -recip_kdf and -recip_ukm parameters to `openssl cms -encrypt`
to allow the user to specify the KDF algorithm and optional user
keying material for each recipient.
A provider may indicate which RecipientInfo type is supported
for a key, otherwise CMS will try to figure it out itself. A
provider may also indicate which KDF to use in KEMRecipientInfo

This is useful for AEAD ciphers where it is not possible to use AEAD
cipher (currently only AES GCM supported) for password recipient info
because the same cipher is used for encrypting the password and it is
not possible to store tag for this purpose so different cipher (e.g.
AES CBC) needs to be selected.

Signature schemes like Ed25519 or ML-DSA use "pure" signing,
i.e. they directly sign the tbs data instead of signing a digest.
This is already supported in the X509 code, but not in CMS.
This commit adds support for such schemes to CMS.
This is a minimalistic set of changes, based in the work done
by David von Oheimb.

Previously there was no way to create a CMS SignedData signature without a
signing time attribute, because CMS_SignerInfo_sign added it unconditionally.
However, there is a use case (PAdES signatures) where this attribute is not
allowed, so this commit introduces a new flag to the CMS API that causes this
attribute to be omitted at signing time.
Also add -no_signing_time option to cms command.

When successful, ossl_X509_ALGOR_from_nid() returns a pointer to an
X509_ALGOR object. Inside ossl_X509_ALGOR_from_nid(),
X509_ALGOR_set0() is called, and this passes ownership of the ASN1
object "los" (label octet string) to the X509_ALGOR object. When
ossl_X509_ALGOR_from_nid() fails, ownership has not been passed on and
we need to free "los".
Change the scope of "los" and ensure it is freed on failure (on
success, set it to NULL so it is not freed inside the function).
