Provides an interface for form element plugins.
Form element plugins are a subset of render elements, specifically representing HTML elements that take input as part of a form. Form element plugins are discovered via the same mechanism as regular render element plugins. See \Drupal\Core\Render\Element\ElementInterface for general information about render element plugins.
