#2851635: DefaultSingleLazyPluginCollection retains stale instance IDs →
shows that base plugin classes should all merge default configuration in the same way. We should make it easy to implement \Drupal\Component\Plugin\ConfigurableInterface.
Add new trait and base class and use it where appropriate in core.
Additionally, since the use of this interface requires some work to be done in the constructor, add a base class which does that work in the constructor. Not all plugins will be able to use the base class, as they may need to extend a different class, but it will be useful for those that can. Those that can cannot use the base class can use the trait and reimplement the constructor logic in their own constructor.
Specifically:
Add
Drupal\Component\Plugin\ConfigurableTraitDrupal\Core\Plugin\ConfigurablePluginBaseUse the new base class in the following classes:
Drupal\Core\Display\VariantBaseDrupal\Core\Layout\LayoutDefaultDrupal\image\src\ImageEffectBaseDrupal\workflows\src\Plugin\WorkflowTypeBaseUse the new trait in the following classes:
Drupal\Core\Action\ConfigurableActionBaseDrupal\Core\Condition\ConditionPluginBaseDrupal\search\src\Plugin\ConfigurableSearchPluginBaseAdjust related tests as needed, and add Drupal/Tests/Component/Plugin/ConfigurableTraitTest.
\Drupal\Component\Plugin\PluginBase.setConfiguration() still needs to be overridden in WorkflowTypeBase.None
New trait
