Upgrade `_WP_List_Table_Compat` to PHP5-style constructor.

Add `public` to methods/members of `WP_Role`.
Add `public` to methods/members of `WP_User` where appropriate. Don't set `private` where indicated until more study has occurred and tests have been written for compatibiliy with existing magic methods.

See #27881, #22234.

`WP_Query` was only missing one access modifier.

Add access modifier (`public`) to applicable class methods/members of `WP_Rewrite`. I am not brave enough to set some of the `var`s to `private` without more testing.
