Unit Tests: implement setUpBeforeClass() and tearDownAfterClass() on WP_UnitTestCase. Use late static binding (plus a gross fallback for PHP 5.2) to check if wpSetUpBeforeClass() or wpTearDownAfterClass() exist on the called class, and then call it and pass a static WP_UnitTest_Factory instance via Dependency Injection, if it exists.

This makes it way easier to add fixtures, and tear them down, without needing to instantiate WP_UnitTest_Factory in every class - removes the need to call commit_transaction() in each individual class.

See #30017, #33968.
