[54214] added the `wp_enqueue_stored_styles()` tests and `clean_up_global_scope()` reset global method to `Tests_Theme_wpGetGlobalStylesheet`.
This changeset relocates those tests a new test class specifically for `wp_enqueue_stored_styles()` and removes `Tests_Theme_wpGetGlobalStylesheet::clean_up_global_scope()` method.
Why not relocate the `clean_up_global_scope()` method to the new test class?
The test class extends from `WP_Theme_UnitTestCase` which includes this method.
Follow-up to [54214], [54703].
Props costdev.
