ba6ae923b5 Script Loader: Load the modules to the footer in classic themes
Incremental import maps fail if the import map is printed after the module scripts.
This means, we should always render import maps first. This means that for classic themes, we need to move the import map and modules to the footer because we can't know before that which modules are needed.

82d1434124 Script Modules API: Rename wp_module to wp_script_module
Renames all mentions to "module" with "script module", including function names, comments, and tests.

Follow up to [57269]

The list of functions renamed are:

 - `wp_module()`          -> `wp_script_module()`.
 - `wp_register_module()` -> `wp_register_script_module()`.
 - `wp_enqueue_module()`  -> `wp_enqueue_script_module()`.
 - `wp_dequeue_module()`  -> `wp_dequeue_script_module()`.
 - `WP_Script_Modules::print_enqueued_modules()` -> `WP_Script_Modules::print_enqueued_script_modules()`.
 - `WP_Script_Modules::print_module_preloads()`  -> `WP_Script_Modules::print_script_module_preloads()`.

It also adds PHP 7 typing to all the functions and improves the types of the `$deps` argument of `wp_register_script_module()` and `wp_enqueue_script_module()` using `@type`.

36f543f447 JavaScript: Add new Modules API.
This changeset adds a new API for WordPress, designed to work with native ES Modules and Import Maps. It introduces functions such as `wp_register_module`, and `wp_enqueue_module`.

The API aims to provide a familiar experience to the existing `WP_Scripts` class, offering similar functionality. However, **it's not intended to duplicate the exact functionality of `WP_Scripts`**; rather, it is carefully tailored to address the specific needs and capabilities of ES modules.

For this initial version, **the current proposal is intentionally simplistic**, covering only the essential features needed to work with ES modules. Other enhancements and optimizations can be added later as the community identifies additional requirements and use cases.

== Differences Between WP_Script_Modules and WP_Scripts

=== Dependency Specification

With `WP_Script_Modules`, the array of dependencies supports not only strings but also arrays that include the dependency import type (`static` or `dynamic`). This design choice allows for future extensions of dependency properties, such as adding a `version` property to support "scopes" within import maps.

=== Module Identifier

Instead of a handle, `WP_Script_Modules` utilizes the module identifier, aligning with the module identifiers used in JavaScript files and import maps.

=== Deregistration

There is no equivalent of `wp_deregister_script` at this stage.

== API

=== `wp_register_module( $module_identifier, $src, $deps, $version )`

Registers a module.

{{{
// Registers a module with dependencies and versioning.
wp_register_module(
  'my-module',
  '/path/to/my-module.js',
  array( 'static-dependency-1', 'static-dependency-2' ),
  '1.2.3'
);
}}}

{{{
// my-module.js
import { ... } from 'static-dependency-1';
import { ... } from 'static-dependency-2';

// ...
}}}

{{{
// Registers a module with a dynamic dependency.
wp_register_module(
  'my-module',
  '/path/to/my-module.js',
  array(
    'static-dependency',
    array(
      'id'     => 'dynamic-dependency',
      'import' => 'dynamic'
    ),
  )
);
}}}

{{{
// my-module.js
import { ... } from 'static-dependency';

// ...
const dynamicModule = await import('dynamic-dependency');
}}}

=== `wp_enqueue_module( $module_identifier, $src, $deps, $version )`

Enqueues a module. If a source is provided, it will also register the module.

{{{
wp_enqueue_module( 'my-module' );
}}}

=== `wp_dequeue_module( $module_identifier )`

Dequeues a module.

{{{
wp_dequeue_module( 'my-module' );
}}}

== Output

- When modules are enqueued, they are printed within script tags containing `type="module"` attributes.
- Additionally, static dependencies of enqueued modules utilize `link` tags with `rel="modulepreload"` attributes.
- Lastly, an import map is generated and inserted using a `<script type="importmap">` tag.

{{{
<script type="module" src="/path/to/my-module.js" id="my-module"></script>
<link rel="modulepreload" href="/path/to/static-dependency.js" id="static-dependency" />
<script type="importmap">
  {
    "imports": {
      "static-dependency": "/path/to/static-dependency.js",
      "dynamic-dependency": "/path/to/dynamic-dependency.js"
    }
  }
</script>
}}}

== Import Map Polyfill Requirement

Even though all major browsers already support import maps, an import map polyfill is required until the percentage of users using old browser versions without import map support drops significantly.

This work is ongoing and will be added once it's ready. Progress is tracked in #60232.
