Access Modifiers:

* In `WP_Plugin_Install_List_Table`, use `public` instead of `var`
* In `WP_User`, `->data` is accessed directly on an instance if the constructor receives it: make it `public`
* In `WP_Locale`, every property is exported to a global and is already `public` via `var`, half of the properties are accessed directly already, make them all `public`
* In `WP_Rewrite`, several properties are accessed publicly in functions via the `$wp_rewrite` global, make those props `public`.
* In `WP_Rewrite`, the property `->comment_feed_structure` was misspelled as `->comments_feed_structure`

See #30799.
