QueueWorkerBase should inherit from Core's PluginBase, not Component's

Problem/Motivation

I have a QueueWorker class that I'd like to autowire in 11.3.x, but because QueueWorkerBase inherits directly from Drupal\Component\Plugin\PluginBase instead of Drupal\Core\Plugin\PluginBase, it does not use AutowiredInstanceTrait, nor does it have a ready-built create() method.

Steps to reproduce

1. Create a new class, under modules/contrib/mymodule/src/Plugin/QueueWorker, inheriting from QueueWorkerBase, and implementing ContainerFactoryPluginInterface.
2. Add a constructor:
   

     public function __construct(
       array $configuration, $plugin_id, $plugin_definition,
       protected EntityTypeManagerInterface $entityTypeManager,
     ) {
       parent::__construct($configuration, $plugin_id, $plugin_definition);
     }
   

3. Note that you have to write your own create() method. There is no auto-wiring. The best-case scenario is to use AutowiredInstanceTrait and then copy the create method from Drupal\Core\Plugin\PluginBase.

Proposed resolution

Make QueueWorkerBase inherit from Drupal\Core\Plugin\PluginBase instead of Drupal\Component\Plugin\PluginBase
