cellref: Add json dump 
New `help -dump-cells-json <file>` to dump cells list.
Add 'group' field to SimHelper class/struct with defaults to gate_other and word_other depending on source (simcells or simlib).

Krystine Sherwin 21747c468c
Docs: Improve cell_help usage 
- Drop `cell_code` and instead map code lookups to the `cell_help` dict.
- Add helper functions to struct for checking and getting the right cell.
- Add `CellType` for cell to `write_cell_rst` function declaration in
  preparation for use in future.
- Iterate over `yosys_celltypes.cell_types` when exporting cell rst files,
  reporting errors for any cells defined in `cell_types` but not
  `cell_help_messages`.

cellhelp: Add default format parse for simcells 
Since `simcells.v` uses consistent formatting we can handle it specifically to help tidy up sphinx warnings about the truth tables, and instead chuck them in a code block which when printing to rst.
Also has the side effect that rst code blocks can be added manually with `//- ::` followed by a blank line.

cellhelp: Add source line to help

Docs: Put cell library help strings into a struct 
Allows for more expressive code when constructing help messages for cells.
Will also move extra logic in parsing help strings into the initial python parse instead of doing it in the C++ at export time.

wheels: fix missing yosys-abc/share directory 
* `misc/__init__.py`:
  * checks if there's a `yosys-abc` in the same directory - if yes, sets the variable `sys._pyosys_abc`
  * checks if there's a `share` in the same directory - if yes, sets the variable `sys._pyosys_share_dirname`
* `yosys.cc::init_share_dirname`: check for `sys._pyosys_share_dirname`, use it at the highest priority if Python is enabled
* `yosys.cc::init_abc_executable_name`: check for `sys._pyosys_abc`, use it at at the highest priority if Python is enabled
* `Makefile`: add new target, `share`, to only create the extra targets
* `setup.py`: compile libyosys.so, yosys-abc and share, and copy them all as part of the pyosys build
* `test/arch/ecp5/add_sub.py`: ported `add_sub.ys` to Python to act as a test for the share directory and abc with Python wheels, used in CI

Pyosys Wheels 
* Created `setup.py`: Python package manifest to build `pyosys` wheels with a custom extension to build and include `libyosys.so` using Make
* `.gitignore`: Added byproducts of the Python wheel build process
* `Makefile`: Added `-undefined dynamic_lookup` to `libyosys.so` so missing symbols can be resolved by importing into a Python interpreter
* `kernel/yosys.cc`: Gated `PyImport_AppendInittab` with `!Py_IsInitialized`; as of Python 3.12, the interpreter is already initialized and `PyImport_AppendInittab` would cause an exception to be raised
* Created `wheels.yml`: CI workflow for building wheels for CPython on:
  * Linux (glibc, musl) and Darwin
  * x86-64 and arm64

cli/python: error-checking, python interpreter bugfix 
* Less brittle method of adding script dirname to sys.path

Martin Povišer 3e3515e7d9 log: Never silence `log_cmd_error` 
Add extra handling to arrange for `log_cmd_error` never being silenced
by the command line `-v N` option. Similar path for `log_error` exists
already.

Add dirname of script file to sys.path 
This matches the behavior of running a Python interpreter, where the
first element of sys.path is the dirname of the script being run.

This allows importing of files and modules in the same directory without
messing with PYTHONPATH or similar.

-y flag for libyosys Python scripts 
This adds a Python equivalent to the `-c` option, where scripts importing `libyosys` can be imported and used.

Most of the work for this was already done to enable Python passes a couple years back, so this is a relatively small changeset.
