Refactor command menu items deprecated code (#19508)

- Removes the intermediate `CommandMenuItemConfig` /
`CommandConfigContext` / `CommandMenuItemDisplay` abstraction layers,
replacing them with a single `CommandMenuItemRenderer` that renders
directly from the command menu items from the backend
- Eliminates the server-items/ subdirectory by moving its contents
(hooks/, contexts/, states/, display/, edit/) up into the parent
command-menu-item/ module, removing an unnecessary nesting level.
