870ae18a2d Switch the SigSpec packed representation to allow just a single chunk that's inline in the SigSpec.
Single-chunk SigSpecs are very common and this avoids a heap allocation. It also simplifies
some algorithms.

a69d48dd19 Instead of using packing and hashing to compute SigSpec ordering and equality, just use the width and chunkwise comparisons
This avoids having to pack and compute hashes, and generally results in a
simpler ordering.

pyosys: fix regressions from 0.58
- consistently use value semantics for objects passed along FFI boundary
  (not ideal but matches previous behavior)
- add new overload of RTLIL::Module: addMemory that does not require a "donor" object
  - the idea is `Module`, `Memory`, `Wire`, `Cell` and `Process` cannot be directly constructed in Python and can only be added to the existing memory hierarchy in `Design` using the `add` methods - `Memory` requiring a donor object was the odd one out here
- fix superclass member wrapping only looking at direct superclass for inheritance instead of recursively checking superclasses
- fix superclass member wrapping not using superclass's denylists
- fix Design's `__str__` function not returning a string
- fix the generator crashing if there's any `std::function` in a header
- misc: add a crude `__repr__` based on `__str__`

2f81c55389 Make mfp const methods thread-safe.
In particular, we make the parent links relaxed atomics so concurrent
`ifind()` calls are safe.

This may appear to cause a tiny performance regression but as discussed
in https://yosyshq.discourse.group/t/parallel-optmergepass-implementation/87/16
this is probably just noise.

misc: WITH_PYTHON -> YOSYS_ENABLE_PYTHON
For consistency.

Also trying a new thing: only rebuilding objects that use the pybind11 library. The idea is these are the only objects that include the Python/pybind headers and thus the only ones that depend on the Python ABI in any capacity, so other objects can be reused across wheel builds. This has the potential to cut down build times.

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

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.
