WIP: Move several extensions to WP stubs

[IanDelMar]

Description

This pull request syncs the 2.x branch with the master branch and removes extensions whose functionality has already been implemented or is about to be implemented by php-stubs/wordpress-stubs, or is no longer needed or is incorrect:

• EchoKeyDynamicFunctionReturnTypeExtension
• GetApprovedCommentsDynamicFunctionReturnTypeExtension
• GetListTableDynamicFunctionReturnTypeExtension
• GetPostDynamicFunctionReturnTypeExtension
• GetPostsDynamicFunctionReturnTypeExtension
• GetSitesDynamicFunctionReturnTypeExtension
• GetTermsDynamicFunctionReturnTypeExtension
• WpDieDynamicFunctionReturnTypeExtension
• WpThemeMagicPropertiesClassReflectionExtension

EchoKeyDynamicFunctionReturnTypeExtension

• Only the_title_attribute(), wp_dropdown_languages(), wp_get_archives(), wp_list_bookmarks(), wp_list_categories(), and wp_list_pages() have been transferred to php-stubs/wordpress-stubs.
• wp_dropdown_categories(), wp_dropdown_pages(), wp_dropdown_users(), and wp_link_pages() always return a string as documented, and hence are not included in any PR porting functionality to php-stubs/wordpress-stubs.
• The $args parameter of get_search_form(), wp_list_authors(), wp_list_comments(), wp_list_users(), wp_login_form(), and wp_page_menu() is filterable, and thus the value of $args['echo'] is unknown. Therefore, these were excluded from the functionality ported to php-stubs/wordpress-stubs.

RedirectCanonicalDynamicFunctionReturnTypeExtension

Starting from PHPStan 1.10.49, void types, including void in unions, are transformed into null. This extension is no longer needed.

All right.
Please help me review it.

All right. Please help me review it.

Although it may not seem like it, there isn't actually much to review. This PR removes some of the extensions that have been ported to WP stubs. The remainder is simply an import of recent changes (from the last two months) in the master branch.
