QFile::supportsMoveToTrash

In our app, we need to know if moving to a system trash is supported.

As a workaround, we can create a temporarily file and then try to delete it using QFile::moveToTrash. 

But, this is not very good and convenient. Instead, I would like to be able to use some API like static bool QFile::supportsMoveToTrash() or QStorage(xxx).supportsMoveToTrash().
