Add validation error source attribution for script translations and wp_editor()

[westonruter]

Summary

Given a site in Transitional mode, with the and the bbPress plugin active there being an “Interesting Stuff” forum created, as well as an “Enqueue Foo” plugin active that does the following:

<?php
/**
 * Plugin Name: Enqueue Foo
 */

add_action(
	'wp_enqueue_scripts',
	function () {
		wp_register_script( 'bar', plugin_dir_url( __FILE__ ) . 'bar.js', [], false, true );
		wp_set_script_translations( 'bar', 'bar' );

		wp_enqueue_script( 'foo', plugin_dir_url( __FILE__ ) . 'foo.js', [ 'bar' ], false, true );
		wp_set_script_translations( 'foo', 'foo' );
	}
);

Attempting to validate a singular forum page at /forums/forum/interesting-stuff/amp/ results in the following difference with this PR:

Before	After

Instead of scripts being unexpectedly attributed to wp-includes:

• Script translations are now properly attributed to the plugin that caused them to be added to the page. Fixes Script translations lack source attribution  #4750.
• When a template file causes a script to be enqueued (as opposed to a hook) specifically in the case of bbPress calling wp_editor(), the editor scripts are now attributed to the plugin that caused them to be added. Fixes Site scanner Inconsistencies. #6668.
