While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.
This commit:
* Renames the `$echo` parameter to `$display` in:
* `wp_popular_terms_checklist()`
* `_post_states()`
* `_media_states()`
* Renames the `$default` parameter to `$default_term` in `wp_popular_terms_checklist()`.
* Renames the `$default` parameter to `$default_template` in `page_template_dropdown()`.
* Renames the `$default` parameter to `$default_page` in `parent_dropdown()`.
* Renames the `$object` parameter to `$data_object` in:
* `do_block_editor_incompatible_meta_box()`
* `do_meta_boxes()`
* `do_accordion_sections()`
* Amends the `$item_object` parameter in other functions for consistency:
* `wp_nav_menu_item_post_type_meta_box()`
* `wp_nav_menu_item_taxonomy_meta_box()`
* `_wp_nav_menu_meta_box_object()`
