fix: After enabling the long file name function, delete files to the trash. Right click on the attribute window and there is marked information that can be edited

All trash files cannot be marked. Register the hook_cantag function and return a tag that is not allowed

关键摘要:

• 在Trash::followEvents函数中，searchPlugin变量被声明但未使用，应考虑移除或添加相关代码以使用该变量。
• Trash::bindWindows函数中缺少对DPF_NAMESPACE::Listener实例的声明，可能导致编译错误。
• TrashFileHelper::handleCanTag函数中，对canTag变量的赋值操作应该在条件判断之后进行，以避免在未赋值的情况下使用。
• TrashFileHelper::handleCanTag函数中的if (canTag)检查是多余的，因为*canTag已经被初始化为false。
• TrashFileHelper::handleCanTag函数中的if (url.scheme() == scheme() || FileUtils::isTrashFile(url))检查可能存在逻辑错误，应该确认是否需要同时满足两个条件。
