QQuickParticleAffector: Fix warnings about copying non-shared containers

Use range-based for, fixing:
'QtPrivate::warnIfContainerIsNotShared': Do not use foreach/Q_FOREACH with containers which are not implicitly shared. Prefer using a range-based for loop with these containers: `for (const auto &it : container)`, keeping in mind that range-based for doesn't copy the container as Q_FOREACH does
            T=QVarLengthArray<QQuickParticleGroupData *,32> &

            T=QQuickParticleVarLengthArray<QQuickParticlePainter *,4> &
