Fix NULL deference when validating FFC public key.

Fixes CVE-2023-0217

When attempting to do a BN_Copy of params->p there was no NULL check.
Since BN_copy does not check for NULL this is a NULL reference.

As an aside BN_cmp() does do a NULL check, so there are other checks
that fail because a NULL is passed. A more general check for NULL params
has been added for both FFC public and private key validation instead.

Use as small dh key size as possible to support the security

Longer private key sizes unnecessarily raise the cycles needed to
compute the shared secret without any increase of the real security.

We use minimum key sizes as defined in RFC7919.

For arbitrary parameters we cannot know whether they are safe
primes (we could test but that would be too inefficient) we have
to keep generating large keys.

However we now set a small dh->length when we are generating safe prime
parameters because we know it is safe to use small keys with them.

That means users need to regenerate the parameters if they
want to take the performance advantage of small private key.

Add multiple fixes for ffc key generation using invalid p,q,g parameters.

Fixes #11864

- The dsa keygen assumed valid p, q, g values were being passed. If this is not correct then it is
possible that dsa keygen can either hang or segfault.
The fix was to do a partial validation of p, q, and g inside the keygen.
- Fixed a potential double free in the dsa keypair test in the case when in failed (It should never fail!).
It freed internal object members without setting them to NULL.
- Changed the FFC key validation to accept 1024 bit keys in non fips mode.
- Added tests that use both the default provider & fips provider to test these cases.

Add ACVP fips module tests

For FIPS validation purposes - Automated Cryptographic Validation Protocol (ACVP) tests need to be
performed. (See https://github.com/usnistgov/ACVP). These tests are very similiar to the old CAVS tests.

This PR uses a hardwired subset of these test vectors to perform similiar operations,
to show the usage and prove that the API's are able to perform the required operations.
It may also help with communication with the lab (i.e- The lab could add a test here to show
a unworking use case - which we can then address).

The EVP layer performs these tests instead of calling lower level API's
as was done in the old FOM.
Some of these tests require access to internals that are not normally allowed/required.

The config option 'acvp_tests' (enabled by default) has been added so that this
access may be removed.

The mechanism has been implemented as additional OSSL_PARAM values that can be set and get.
A callback mechanism did not seem to add any additional benefit.
These params will not be added to the gettables lists.

Fix DH_get_nid() so that it does not cache values.

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.
