Subject: [PATCH] Twenty Twenty: Remove various unused function parameters and
 variables.

This removes the `$n` variable from `TwentyTwenty_Walker_Page` class `start_el()` function, removes an unused global and the last parameter from
`twentytwenty_filter_wp_list_pages_item_classes()` and `twentytwenty_add_sub_toggles_to_main_menu()`.

Props upadalavipul, sabernhardt, mukesh27.
Fixes #57371.
