Script Loader: Add support for HTML 5 "async" and "defer" attributes.

This allows developers to register scripts with an intended loading strategy by changing the `$in_footer` parameter of `wp_register_script` and `wp_enqueue_script` to an array that accepts both an `in_footer` and `strategy` argument. If present, the loading strategy attribute will be added to the script tag when that script is printed to the page as long as it is not a dependency of any blocking scripts, including any inline scripts attached to the script or any of its dependents.

Fixes #12009.
