Peter Wilson 06c51c0042 Menus: Fix notices thrown by classes extending `Walker_Nav_Menu`. 
Methods in `Walker_Nav_Menu` can be called with multiple, incompatible `$args` objects so an `insset()` check is required to avoid throwing notices.

Introduced in [38523].

Fixes #35206.

John Blackbourn 8bec516c18 Menus: Correct the docblocks for `Walker_Nav_Menu`, `wp_nav_menu()`, and `walk_nav_menu_tree()`. 
This corrects the parameter type for the `$args` and `$item` parameters passed throughout these functions, class methods, and hooks.

See #24587

Peter Wilson 4131900722 Menus: Add white space option to `wp_nav_menu()` and `wp_list_pages()`. 
Adds an `item_spacing` option to the arguments array for the functions `wp_nav_menu()`, `wp_list_pages()`, and `wp_page_menu()`. `item_spacing` is a boolean accepting either `preserve` or `discard`.

Previously, certain CSS choices could result in a site's layout changing if `wp_nav_menu()` fell back to the default `wp_list_pages()` due to differences in the whitespace within the HTML. The new argument ensures a function outputs consistant HTML while maintaining backward compatibility.

Fixes #35206.

The new class-walker-nav-menu.php file is loaded in nav-menu-template.php for backward compatibility purposes.
