Remove LHCb::State::clone()
- State is a concrete, final class, and does not inherit from anything, and nothing can inherit from it. So there is no reason to provide a (non-virtual) clone method.
- This commit thus removes LHCb::State::clone
- Rec!1284 (merged) removes the remaining usage of LHCb::State::clone, so this MR should be accepted either together, or after Rec!1284 (merged)
