Update tests to use Junit 5

Tests have been updated to use Junit5. Changes made include:
- Removing the `junit-vintage-engine` dependency. This is no longer
in use given all tests now make use of Junit 5.
- Tests are sorted by alphabetical in test suites.
- Tests no longer need to extend `junit.framework.TestCase`.
- Tests are explicitly declared with the `@Test` annotation.
- Test constructors have been removed. Arguments to the base tests are
now sent using getters and setters. This is typically only used for
setting providers, algorithms, or key sizes in tests.
- Various `main()` methods of tests were removed as they are no longer
in use. Tests can be run using various Junit 5 test execution tools
such as IDEs, command line tools, and `mvn` surefire which is already
in place in this project.
- `BaseTest` was removed as it is no longer in use and represents a
Junit 3 test. A new `BaseTestJunit5` test has been created to represent
the new base for the test hierarchy.
- The concept of warming up a test has been removed from a few
locations. Tests are not expected to act as performance tests.
- Copyrights were updated.
- Various empty comment blocks were removed.
- Some tests were not executing using the expected provider since the
incorrect `Utils` class was in use. This was corrected to use the
correct class.
- Tests `TestAESGCM_192`, `TestAESGCM_256`, and `TestRSA_4096` were
added to the `OpenJCEPlus` and `OpenJCEPlusFIPS` provider test suites.
- Tests `TestECDHInteropBC`, `TestRSATypeCheckEnabled`, `TestAES_192`,
and `TestAES_256` were added to the `OpenJCEPlus` provider test suite
- Tests `TestAES_192` and `TestAES_256` were removed from the
`TestMultithreadFIPS` since these tests take a long period of time to
complete. Coverage functionally is still maintained since they are
executed as part of the `OpenJCEPlusFIPS` provider tests.
- Increased timeouts associated with tests `TestMultithreadFIPS` and
`TestMultithread`.
