Class TaxonomyEntityIndexTidDepth is missing a create() method

While the TaxonomyEntityIndexTidDepth class is using proper dependency injection in overriding core, which isn't, the constructors differ. This is because we're injecting the database service.

While that's great, callers aren't expecting the different number of parameters leading to this error:

TypeError: Argument 5 passed to Drupal\taxonomy_entity_index\Plugin\views\argument\TaxonomyEntityIndexTidDepth::__construct() must be an instance of Drupal\Core\Database\Connection, none given, called in /path/to/drupal/web/core/modules/taxonomy/src/Plugin/views/argument/IndexTidDepth.php on line 43 in Drupal\taxonomy_entity_index\Plugin\views\argument\TaxonomyEntityIndexTidDepth->__construct() (line 36 of /path/to/taxonomy_entity_index/src/Plugin/views/argument/TaxonomyEntityIndexTidDepth.php)

To fix, we need to add a create() method, which adds this missing service dependency. Callers use this instead of the constructor if it's available.

Patch forthcoming.
