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 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.
