Fix incorrect event dependency of GPU update

With separate PME ranks, staged communication and GPU update, the final
forces are produced on the CPU and re-uploaded to the GPU prior to
update. This upload was done on a "All" locality leading to an incorrect
dependency on an event corresponding to the GPU reduction.
This leads ot a logic error and incorrect synchronization, but not
incorrect results as the "All" locality copy is done on the update
stream, hence implicit dependency applies.

This change moves this special case copy to the same locality used in
other force host to device copies to eliminate the bug.

Use ObservablesReducer for check of DD bonded interaction count.

The lifetime of the local and global state has been shifted, so that
the LocalTopologyChecker can now be initialized with the handles it
might need to use to report an error, even though one of those handles
will not contain valid data until after the first DD partition.

This simplifies ComputeGlobalsElement from the modular simulator.

The changes to StatePropagatorData motivated by this change reduce the
number of copies of x and v vectors that were being done every
partitioning step. Those are needed only when the state backup is
taken so that trajectory output can be handled correctly.

The check is now implemented for minimizers, where previously it
was not.
