Customizer: Introduce `customize_nav_menu_available_item_types` and `customize_nav_menu_available_items` filters. 

Allows for new available menu item types/objects to be registered in addition to filtering the available items that are returned for each menu item type/object.

Props valendesigns, imath, westonruter.
See #32832.
Fixes #32708.
