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
