interface ExposedFormPluginInterface in Drupal 10

Interface for exposed filter form plugins.

Exposed form plugins handle the rendering, validation, and submission of exposed forms, and may add additional form elements. These plugins can also alter the view query. See \Drupal\views\Plugin\views\exposed_form\InputRequired as an example of that functionality.
