Add support for deferred FIPS self-tests

Add support for deferred FIPS self-tests

Add a new -defer_tests option to openssl fipsinstall and a corresponding
defer-tests configuration parameter for the FIPS provider.

This allows the execution of self-tests to be postponed until the
first time an algorithm is used, instead of running all tests
during module initialization. This reduces startup time.

Update the self-test framework to handle the new SELF_TEST_STATE_DEFER
state, ensuring deferred tests are skipped at load and run on demand.
