Adding the EVP_PKEY_param_check_quick() reminded me that there are also
partial checks for public keys as part of SP800-56A for FFC (DH named safe
prime groups) and ECC. The code was mainly already there and just needed
to be plumbed into the validate methods.

EVP_PKEY_CTX_set_dh_ functions were only available when DH was enabled
('no-dsa' not configured). However, that makes it impossible to use
these functions with an engine or a provider that happens to implement
DH. This change solves that problem by shuffling these functions to
more appropriate places.
By consequence, there are a number of places where we can remove the
check of OPENSSL_NO_DH. This requires some re-arrangements of
internal tables to translate between numeric identities and names.
Partially fixes #13550

Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.
The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

This macro is used to determine if certain pieces of code should

DH_set0_pqg() is now responsible for caching the nid, q and length.
DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1)
when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation.
The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be
in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p.
Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names).
The BIGNUMS were code generated.

Fixes #11108.
It only sets q if a valid named group is found.
The function signature was recently changed to pass a non const DH pointer
in order to allow the nid to be cached internally. As an extension of this
the value of q can now also be set as q is always known for named groups.
The length field is also set if q is set.
