Feature #3114: Improve GPU update-constraints module
avoid calling GPU update setup is every search step
In md.cpp integrator->set() is called every search step even without DD which is an expesive call both on the CPU but especially on the GPU side and should be avoided unless repartitioning requires it.

That's a hack around it.
I had a (semi-)proper fix that did not make it into 2020 (https://gerrit.gromacs.org/c/gromacs/+/14897).
Should we use the above linked hack or do something better for 2020?
