add support for packing T::Selection, for classes T which are packable,  if T::Selection is defined

See merge request !4193

this allows a Relation of Particle -> VertexBase to be created
from links to a container of RecVertex (which derives from VertexBase)
by explicitly recognizing that the target container is not a container of
VertexBase, and trying whether it is a container of RecVertex instead

and make `unpack` return a StatusCode to know when an unpacker has
failed, in which case, if available, another unpacker for the same
CLID can be tried

- in addition, for backwards-compatibility, add fall-back
  in case a SharedObjectsContainer is requested to be unpacked,
  but a KeyedContainer is packed
