Catherine afc0e78d11 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).

Philippe Sauter c89cfe1e6e 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.

check_mem: Add -non-const option 
Can identify potentially dangerous addressing, but also prone to false-positives.

Add check_mem command 
Comes with a set of tests which (currently) pass with `read_verilog` but fail with `verific` based on #5878.
Add `--check-sv`, an alternative to `--prove-sv` with generator defined yosys commands.  Helpful for when you want to run the same set of commands on a bunch of sv files.

simplemap: Moves $pmux mapping from techmap.v to simple map 
This Fixes the slow downs I observed in techmap.v, which we
attempted to fix via the simplify ast.h route originally. This
turned out to be rather complex though.

By moving $pmux to simplemap we can just avoid that code. My
test case now runs in 310s which is 40s faster than the baseline
change.
