Update Qt demo app SRCREVs

Update Qt demo app SRCREVs

Update Qt demo app SRCREVs to pick up their Qt6 updates, and drop the
now unnecssary Qt6 patches.  Also, the MapBox configuration support
has been removed from the ondemandnavi-config recipe, as that backend
is no longer supported by QtLocation in Qt6.
