Add pyngspice Python bindings with targeted capacitor probing
Initial commit of the pyngspice layer on top of ngspice:
- pybind11 C++ bindings (src/cpp/, src/bindings/)
- Python package with SpiceRunner interface, netlist preprocessor
- Targeted capacitor probing via .save i(C_name) directives for
fast simulation when only specific cap currents are needed
- Build system (CMakeLists.txt, pyproject.toml, build_mingw.py)
- Test suite with 70 tests covering all preprocessor features
- Examples, winflexbison tooling, CLAUDE.md project docs

"x64" was hardcoded into aux-digital.bat and is used in the compiling of digital.vcxproj.
That's problematic for trying to compile x86 or ARM64.
This patch makes digital.vcxproj pass the arch as arg2 to aux-digital.bat

Reorder and renovate timer functions taking into account ngspice multiprocessor capabilities
by using available high performance functions first.
Deprecated ftime() still acts as a backup function.
Solution is portable for today's operating systems and compilers.

Add support for including Verilog simulation within an instance
of the d_cosim codemodel, using libvvp, the simulation runtime of
Icarus Verilog. This complements the existing method using Verilator.
The new source code is built into two binary shared libraries,
ivlng.so (or .DLL) and ivlng.vpi that are loaded during simulation.

Add Windows Visual Studio support for the Isotel d_process xspice digital model. The Isotel mixedsim-master/examples/embedded/motorforce C code needs to have minor changes for _MSC_VER defines, and are not included with this commit. The changes relate to using #pragma pack(push, 1)...#pragma pack(pop) around some structs, and setting stdin/stdout in binary mode. It is doubtful that the cfunc.mod will compile on mingw or cygwin since I don't know if they support pipe/fork/exec/spawn calls. The code builds and runs on Windows, Linux, and MacOS. In the future, Giles Atkinson is looking at allowing Xspice models to load shared libraries (.dll, .so) which will avoid creating and communicating with an external program.
