Build/Test Tools: Add support for PHPUnit 7.x.

* Create an abstract `WP_UnitTestCase_Base` class to share between PHPUnit 7.x and older versions.
* Add a speed-trap loader to determine which `SpeedTrapListener` class needs to be loaded for the current PHPUnit version.
* Remove unnecessary `PHPUnit\Util\Test` and `PHPUnit_Util_Getopt` inheritances.
* Update Travis CI config to use PHPUnit 7.x for PHP 7.1, 7.2, and nightly PHP versions.
