Control the list of behaviors run by Drupal.attachBehaviors

Comes up periodically that people want to alter the order of behaviors being run or only run a few of them. Instead of modifying Drupal.behaviors object we should have a way of controlling that explicitly (came up in #2362637: Editor.js attach/detach doesn't pass context all the way down → ). Having this would mean that the behavior system is justified and Drupal can't use events to do it's thing, see #1446166-39: Use JS events instead of Drupal.behaviors → .

Introducing a new parameter, behaviorList, and a new function Drupal.behaviorList.

Drupal.attachBehaviors(document, drupalSettings, ['AJAX', 'editor', 'formUpdated', 'escapeAdmin']);

// Override default behavior ordering
Drupal.behaviorList = function (event, trigger) { return myCustomOrderedBehaviorsArray; };

Same for Drupal.detachBehaviors. behaviorList defaults to the whole list of behaviors. This can also be used to alter the order in which behaviors are run.
