Yakov Pechersky 872b054d5c Defer numpy initialization to first use (#9127) ...

* Defer numpy initialization to first use in rdchem, rdmolops, cDataStructs

`from rdkit import Chem` unconditionally bootstrapped numpy (~120ms) via
import_array()/boost::python::numpy::initialize() in module init functions,
even when no numpy-dependent APIs were called. This is costly in cold-start
environments like AWS Lambda.

Move numpy initialization behind lazy guards (static bool + first-call init)
in rdchem.so, rdmolops.so, and cDataStructs.so. Numpy now loads only when
an API that actually needs it is invoked (GetDistanceMatrix, GetPositions,
SetPositions, GetAdjacencyMatrix, ConvertToNumpyArray, etc.).

Also change Conformer::SetPos to accept python::object instead of
np::ndarray to prevent Boost.Python from requiring numpy type conversion
before the lazy guard runs.

Adds test_lazy_numpy.py with subprocess-based tests verifying:
- `from rdkit import Chem` does not load numpy
- SmilesToMol/MolToSmiles work without numpy
- numpy loads on demand when array APIs are called

* skip inchi tests if not available

* switch to threadsafe once_flag, like elsewhere

* finish ifdef style

* switch to magic static style

* Revert "switch to magic static style"

This reverts commit 7300188db7.
