[DD4hep] DDFilteredView current volume path and its copy numbers

[ianna]

PR description:

• Add an iterator accessor path that returns a path to a current node. Please, use it sparingly.
• Add an iterator accessor copyNos that returns a vector of the volumes copy numbers along the path. The vector index indicates the volume level, e.g. an index 0 refers to the current volume copy number, an index 1 refers to the current volume's parent copy number and so on.

as requested by @bsunanda

Note: none of the above is needed if the xml selection parts specified in more details.
