This commit reimplements the (no longer recommended) setuptools based
build system using a standards-based in-tree PEP517 build backend.
The implementation is partially based on
https://codeberg.org/ziglang/zig-pypi/src/branch/main/make_wheels.py
which is licensed under BSD-0-clause.
It also adds a new option `YOSYS_BUILD_PYTHON_ONLY` that is available
only if the binary or the library aren't going to be installed, which
turns off these targets entirely, as well as some dependent ones
(e.g. tests).

The manylinux2014 image provides Python 3.13 and a GCC toolchain
already configured for glibc 2.17 compatibility, avoiding the
Python 3.6 syntax issues with bare centos:7.

Adds a parallel build-manylinux-wheel job using centos:7 container
with devtoolset-11 alongside the existing Alpine/musl wheel build.
Uses auditwheel to tag wheel as manylinux2014_x86_64.
Made-with: Cursor
The macOS job could upload to the latest release before the Linux
job recreated it, causing the macOS wheel to be lost. Now wait
for the Linux wheel to appear in latest first.

The macos-14 runner ships Python 3.14 by default, producing wheels
incompatible with Python 3.13 environments. Pin to 3.13 using
actions/setup-python and switch to macos-15 for consistency.
Made-with: Cursor
The macOS runner doesn't have ccache or pybind11 pre-installed.
Install ccache via brew and disable ENABLE_PYOSYS since we only
need the binary tarball (not the wheel) for macOS.
Made-with: Cursor
Adds a build-macos job on macos-15 that builds Verific tclmain and
yosys with SMALL=1, bundles non-system dylibs, and uploads
yosys-macos-arm64.tar.gz alongside the existing Linux assets.
Made-with: Cursor
Copies all non-system shared library dependencies into lib/, then
uses patchelf to set RPATH to $ORIGIN/../lib for bin/ executables
and $ORIGIN for lib/ libraries.
Made-with: Cursor
The wheel build uses ENABLE_TCL=0, but the standalone yosys binary
needs ENABLE_TCL=1. Without a clean, stale .o files cause undefined
reference errors for TCL symbols.
Made-with: Cursor
Verific tclmain links -ltcl and -lnsl. Alpine tcl-dev provides
libtcl8.6.so (no libtcl.so symlink), and musl has no libnsl.
Create symlink and stub shared lib to satisfy the linker.

Deploy keys are repo-scoped and can't access multiple private repos.
Use a PAT (SUBMODULE_PAT) that has access to all required repos.
