function views_views_data_alter

Implements hook_views_data_alter().

Field modules can implement hook_field_views_data_views_data_alter() to alter the views data on a per field basis. This is weirdly named so as not to conflict with the \Drupal::moduleHandler()->alter('field_views_data') in views_views_data().
