Font Library: Font Collection backend

[matiasbenedetto]

Follow up of the previous PR: #53816

What?

Add extensibility capabilities to the Font Library.
Provides a way to provide collections of typographic fonts by code.

Why?

• Standardize the way to add font collections to the font library.
• Allows extenders code (plugins, for example) to register lists of fonts to let the user install the ones they want. Font foundries, for example, will be able to create a plugin to provide their fonts with just a few lines of code.

Example:

This is all the code required to create a plugin providing a font collection.

<?php
/*
Plugin Name: My Font Collection
Plugin URI: https://your-website.com/
Description: Add a font collection to your WordPress Font Library.
Version: 1.0
Author: Your Name
Author URI: https://your-website.com/
License: GPLv2 or later
Text Domain: my-font-collection
*/

$my_config = array (
    'id'             => 'my-font-collection',
    'name'           => 'My Font Collection',
    'description'    => 'Demo about how to a font collection to your WordPress Font Library.',
    'data_json_file' => path_join( __DIR__, 'my-font-collection-data.json' ),
);

if ( function_exists( 'wp_register_font_collection' ) ) {
    wp_register_font_collection ( $my_config );
}

?>

Download the plugin as zip ready to test:
my-font-collection.zip

How?

• Implementation of a WP_Font_Collection class.
• Implementation of the wp_register_font_collection filter.
• Implementation of the /fonts/collections and fonts/collections/<id> endpoints.

To do

• Add more ways to provide lists of fonts apart from the JSON file. (maybe for a future PR).
• Add sanitization.
  We would need this: WP_Theme_JSON sanitization is not working below certain level of theme.json #52798

Stage 1: #52698
Stage 2: #53307

Coping my code review from PR #53816:

The source code LGTM 👍

The tests are good enough. I'll follow-up with a test improvement PR.
