Disable autosave for global styles in WordPress

The commit disables the autosave endpoints for the global styles in WordPress. Modifications were made to both post.php and class-wp-post-type.php to prevent autosave for the 'wp_global_styles' post type. This ensures that global Styles does not trigger unnecessary autosaves.
