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.
