Svenn Tveit 32dd09c78f Add Python gas-water simulator and refactor to template base class
Extend the Python blackoil simulator to support two-phase gas-water
simulations by extracting common functionality into a template base
class and implementing proper module separation.

- Extract PyBaseSimulator<TypeTag> template base class containing all
  common simulator functionality (20+ methods including advance, run,
  step, property access, and MPI handling)
- Add PyGasWaterSimulator for two-phase gas-water simulations using
  FlowGasWaterProblem TypeTag with oil phase disabled
- Split Python modules to avoid ODR violations:
  - BlackOil.so for PyBlackOilSimulator (FlowProblemTPFA)
  - GasWater.so for PyGasWaterSimulator (FlowGasWaterProblem)
- Implement proper template instantiation control with explicit
  instantiations per module

- Eliminate ~400 lines of code duplication between simulators
- Clean inheritance hierarchy: derived classes contain only constructors
- Type-safe specialization through OPM's TypeTag property system
- Separate docstring generation for each simulator type
- Independent build targets with shared infrastructure

- Update CMakeLists.txt to support multiple pybind11 modules
- Add docstrings_gw_simulators.json for gas-water simulator documentation
- Remove centralized Pybind11Exporter.cpp in favor of distributed exports
- Implement proper build dependencies and custom targets

This establishes a scalable foundation for extending OPM's Python
bindings to support additional simulator types (thermal, polymer,
solvent) while maintaining type safety and avoiding symbol conflicts.
