configure: require Qt 5 or 6; add --disable-gui for disabling the GUI
This is in preparation of fixing #3137. The plan is not to use
libfile's MIME type detection but Qt's. As both mkvmerge and the GUI
need to auto-detect the MIME type, this means that the command line
applications will have to be linked against Qt's core library (but not
the GUI libraries).
