Migrate build system to CMake

Update top-level Python project for CMake compatibility.
...
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).

peepopt: add shiftpow2 pattern
...
Rewrite power-of-two indexed word selects to $bmux when the shift
amount already carries the scale as low zero bits.
Keep the rule to non-overlapping selections and bound the generated
mux ways. Add regressions for aligned shifts, padding, signed
extension, and shiftmul handoff cases.

verific: Fix negative array dimensions
...
Recurse over memory dimensions once, doing both our min/max address checking and parsing out the initval. This also avoids problems with negative numbers (if `a < b` and one or both are negative, `a` might be the intended `max_addr_chunk`).
Fix sub addressing, where we use some but not all of the current dimension's bits.
