Decouple QApplication from QColormapHEADdev

Initialize the shared QColormapPrivate on first call to
QColormap::instance, in a thread safe manner for good measure,
and clean it up on app exit if needed.

The cleanup now also accounts for the possibility of QColormap
instances outliving the cleanup. We still reset to a new QColormap
on next use, following the existing behavior.
