Before, `wp_localize_script()` did not work when the `$wp_scripts` global was not already set (for example because of a script registration happening elsewhere) and even emitted a warning in that case. Due to side effects such as block registration early in the load process, this usually never happened. However, the absence of these side effects in 6.5 caused the `wp_localize_script()` to no longer work in places such as the `login_enqueue_scripts`. By calling `wp_scripts()` in `wp_localize_script()`, the `$wp_scripts` global is automatically set if needed, restoring previous behavior. Adds both a PHP unit test and an e2e test to verify this use case. Hat tip: jorbin. Happy birthday, Aaron! Props salcode, aslamdoctor, jorbin, swissspidy. Fixes #60862.
