QUIC RX: Refactor unsafe DCID consistency checking

Previously, we enforced the requirement that the DCIDs be the same for
all packets in a datagram by keeping a pointer to the first RXE
generated from a datagram. This is unsafe and could lead to a UAF if the
first packet is malformed, meaning that no RXE ended up being generated
from it. Keep track of the DCID directly instead, as we should enforce
this correctly even if the first packet in a datagram is malformed (but
has an intelligible header with a DCID and length).

Support all five EdDSA instances from RFC 8032

Fixes #6277

Description:
Make each of the five EdDSA instances defined in RFC 8032 -- Ed25519,
Ed25519ctx, Ed25519ph, Ed448, Ed448ph -- available via the EVP APIs.

The desired EdDSA instance is specified via an OSSL_PARAM.

All instances, except for Ed25519, allow context strings as input.
Context strings are passed via an OSSL_PARAM.  For Ed25519ctx, the
context string must be nonempty.

Ed25519, Ed25519ctx, Ed448 are PureEdDSA instances, which means that
the full message (not a digest) must be passed to sign and verify
operations.

Ed25519ph, Ed448ph are HashEdDSA instances, which means that the input
message is hashed before sign and verify.

Testing:
All 21 test vectors from RFC 8032 have been added to evppkey_ecx.txt
(thanks to Shane Lontis for showing how to do that).  Those 21 test
vectors are exercised by evp_test.c and cover all five instances.
