Add checkpoint to DEM solid objects (chaos-polymtl#959)

Description of the problem The moving solid objects used in DEM simulations were not checkpointed at all. This is not good Description of the solution Add the full checkpointing of the solid objects Add a test to ensure that this works correctly How Has This Been Tested? A test has been added to check this feature. It works very well. Documentation I don't think anything needs to be documented in particular here?

+### Fixed
+
+- MINOR Solid objects can now be restarted adequately in DEM. They will resume at the position they had at the end of the simulation [#959](https://github.com/lethe-cfd/lethe/pull/959)
