Users: Share current user instance across functions.

Browse Source 
Share the `WP_User` instance for the current user between the functions `get_userdata()` and `wp_get_current_user()`. Both functions return the `$current_user` global for the current user.

Force refresh the `$current_user` global within `clean_user_cache()` by immediately re-calling `wp_set_current_user()` with the current user's ID. This ensures any changes to the current user's permissions or other settings are reflected in the global. As a side-effect this immediately rewarms the current user's cache.

Fixes #28020.
