Change the meaning of SelectFileDialog.support_drive: it means Drive-aware callers.

More comment? If I understand correctly, Drive is now supported in most cases,
but there would be two ways to handle Drive.

Maybe rename the flag to something more relevant to the new meaning?

Added more comments.
I think the name is still relevant. Turning off the flag indicates
that the caller does not handle Drive files so the file dialog must
do something.

     bool support_drive;
   };
