Super Admin Performance Boost

On a WordPress Multisite, tries to avoid using switch_to_blog() and restore_current_blog() when possible.

Description

1. Short-circuit the get_blogs_of_user() function. We don't have to check if a site is own by the user, we want all sites.
2. Extend WP_MS_Sites_List_Table and use bespoke Super_Admin_Performance_Boost::get_admin_url() and Super_Admin_Performance_Boost::get_home_url() funtions.
3. Extend WP_MS_Users_List_Table
   • For the Super Admin, hide their sites in the Sites column.
   • For rest of the users, use bespoke Super_Admin_Performance_Boost::get_home_url() funtions.

Side note

I wish I did't have to write this and the Super Admin All Sites Menu plugin, but it feels like WordPress Multisite is not ready for the Super Admin role.

I have a multisite with 100+ sites, and the following issues are a pain:

• The My Sites menu doesn't work for more than 23 sites, hence my Super Admin All Sites Menu plugin.
• switch_to_blog() is used on every site for each page load, only to get the blog details, which is a waste of resources.
• There's no point in listing all sites in the Sites column for the Super Admin, they own them all.

Installation

You know the drill.
