Michael Weghorn 8eacf7e372 qt: Have just a single toQString(const OUString&) 
Move the `toQString` helper function to
include/vcl/qt/QtUtils.hxx where it can be used from
multiple modules, instead of defining
it twice for both, avmedia (avmedia/source/qt6/QtPlayer.cxx)
and vcl (vcl/inc/qt5/QtTools.hxx).
