/**
* Prepares a precompiled ContainerBuilder for all tests of this class.
*
* Avoids repetitive calls to ContainerBuilder::compile(), which is very slow.
*
* Based on the (always identical) list of $modules to enable, an initial
* container is compiled, all instantiated services are reset/removed, and
* this precompiled container is stored in a static class property. (Static,
* because PHPUnit instantiates a new class instance for each test *method*.)
*
* This method is not invoked if there is only a single test method. It is
* also not invoked for tests running in process isolation (since each test
* method runs in a separate process).
*
* The ContainerBuilder is not dumped into the filesystem (which would yield
* an actually compiled Container class), because
*
* 1. PHP code cannot be unloaded, so e.g. 900 tests would load 900 different,
* full Container classes into memory, quickly exceeding any sensible
* memory consumption (GigaBytes).
* 2. Dumping a Container class requires to actually write to the system's
* temporary directory. This is not really easy with vfs, because vfs
* doesn't support yet "include 'vfs://container.php'.". Maybe we could fix
* that upstream.
* 3. PhpDumper is very slow on its own.
*
* @param string[] $modules
* The list of modules to enable.
*
* @return \Drupal\Core\DependencyInjection\ContainerBuilder
* A clone of the precompiled, empty service container.
