osmordred: add rdkit217 descriptor set (217 standard RDKit descriptors)

[guillaume-osmo]

Adds the rdkit217 descriptor set — 217 standard RDKit physicochemical/topological descriptors computed in C++, in the exact order of Python's Descriptors._descList.

Independent of the osmordredv3 PR and the smarts291 PR; branches off osmordred.

Contents

• Code/GraphMol/Descriptors/rdkit217/{RDKit217Descriptors.cpp,.h,test_rdkit217.cpp}
• Osmordred.h: declares calcEState_VSA / calcVSA_EState (defined in OsmordredBasicPhyschemCountsRules.cpp) so rdkit217 can reuse the MOE-VSA terms.
• CMake wiring + Python wrapper bindings (ExtractRDKitDescriptors, ExtractRDKitDescriptorsBatch, ExtractRDKitDescriptorsFromMolsBatch, GetRDKit217DescriptorNames) under RDK_BUILD_OSMORDRED.

We already have a way of doing this:

    Properties sink;
    std::vector<std::string> names = sink.getPropertyNames();
     RWMol *mol;
    mol = SmilesToMol("C1CCC2(C1)CC1CCC2CC1");
    std::vector<double> props = sink.computeProperties(*mol);

Might be worth checking to see if it has all 217 descriptors though. Might be missing some.

the idea is was port all descriptors into cpp itself then have a fast generator of them
