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.

verific: Fix non-contiguous memory flattening

May not be the best approach, insofar as it uses empty memory elements for padding out the alignment, but it does avoid costly address arithmetic.
Still needs to adjust ascii init val addresses, but should work fine for read/write accesses.
