pyosys: rewrite wrapper generator

pyosys: rewrite using pybind11 
- Rewrite all Python features to use the pybind11 library instead of boost::python.
  Unlike boost::python, pybind11 is a header-only library that is just included by Pyosys code, saving a lot of compile time on wheels.
- Factor out as much "translation" code from the generator into proper C++ files
- Fix running the embedded interpreter not supporting "from pyosys import libyosys as ys" like wheels
- Move Python-related elements to `pyosys` directory at the root of the repo
- Slight shift in bridging semantics:
  - Containers are declared as "opaque types" and are passed by reference to Python - many methods have been implemented to make them feel right at home without the overhead/ambiguity of copying to Python and then copying back after mutation
  - Monitor/Pass use "trampoline" pattern to support virual methods overridable in Python: virtual methods no longer require `py_` prefix
- Create really short test set for pyosys that just exercises basic functionality

Optimize `IdString::empty()`
 2025-10-01 11:23:59 +02:00
Robert O'Callahan d45223976a Optimize `IdString::empty()` 
I actually saw this take 0.6% of the time in an `opt_clean` pass (under Module::check()).
Trivial issue, but the fix is also trivial and simple.

Robert O'Callahan 915ad949f9 Limit the maximum size of parsed RTLIL constants to 1 Gb. 
Without this check it's trivially easy to crash Yosys with a tiny RTLIL input
by specifying a constant with very large width. Fuzz testers love hitting this
over and over again.
