       Ensure the submitted value is a file upload.

       This Constraint is not needed if you use any of the "File::*" Constraints, as they all make the same
       check as this Constraint does.

       This can only verify that your CGI backend (CGI, Catalyst, CGI::Simple) thinks it was a file upload. If
       the user submits a filename which doesn't exist on their system, you will probably get a valid
       HTML::FormFu::Upload object, with a valid filehandle, but no Content-Length. This Constraint would still
       see this as a valid uploaded file - if you want to ensure that you get a file with content, instead use
       HTML::FormFu::Constraint::File::Size with min set to 1.
