Add wallcycle counting to StatePropagatorDataGpu
Launch overheads are counted in the main GPU launch overhead counter and
a separate subcounter is used for the launch and a main counter for the
CPU blocking wait timing.
Note that this chnge introduces mdtypes->timing->mdtypes cyclic dependency,
the warning on which is suppressed.
Fixes #3207
