nodes: fix serialized ID typos with backward compatibility

- ChromaKey tolerance inputs are now spelled "upper/lower_tolerance_in";
  old projects with the misspelled "tolerence" IDs keep loading (values
  and connections) via a new Node::GetInputIDForLegacyID() hook applied
  in LoadInput and connection deserialization
- flip/ripple/swirl/tile/wave node IDs moved to the consistent
  org.olivevideoeditor.Olive.* domain; NodeFactory::CreateFromID maps
  the old org.oliveeditor.* IDs so old projects still resolve
- Regression tests: legacy ChromaKey IDs (values + connections) and
  legacy factory IDs
