Allows files to be cleaned with `make clean`, without which it breaks out-of-tree builds if an in-tree build has previously run and subsequently cleaned.
- add `uv` to dependencies: saves builder(s) from manually having to manage a venv for python build dependencies
- when building wheels, pip automatically creates the environment with those dependencies, so no need for uv
- when running simply `make ENABLE_PYOSYS=1`, this is not the case. people attempting to `pip3 install --upgrade pybind11 cxxheaderparser` to add it to their system packages will be met with a scare message about "breaking system packages"
- update installation instructions to drop boost and add uv instead
- update ci scripts to use `macos-15[-intel]` (`macos-13` sunset in early december)
For these primitives, Gowin decided to use a different option for
describing ports—directly in the module header, i.e.
``` verilog
module ADC(input CLK);
```
instead of
``` verilog
module ADC(CLK);
input CLK;
```
Since this one-time parser becomes too confusing, it is easier to simply
add ADC descriptions as they are from a separate file, especially since
these primitives are only available in the GW5A series.
Test:
``` shell
yosys -p "read_verilog top.v; synth_gowin -json top-synth.json -family gw5a"
```
The old version of Yosys simply won't compile the design due to the lack
of port descriptions, while the new version will compile without errors.

- consistently use value semantics for objects passed along FFI boundary
(not ideal but matches previous behavior)
- add new overload of RTLIL::Module: addMemory that does not require a "donor" object
- the idea is `Module`, `Memory`, `Wire`, `Cell` and `Process` cannot be directly constructed in Python and can only be added to the existing memory hierarchy in `Design` using the `add` methods - `Memory` requiring a donor object was the odd one out here
- fix superclass member wrapping only looking at direct superclass for inheritance instead of recursively checking superclasses
- fix superclass member wrapping not using superclass's denylists
- fix Design's `__str__` function not returning a string
- fix the generator crashing if there's any `std::function` in a header
- misc: add a crude `__repr__` based on `__str__`
Process the WRITE_MODE in the GW5A series in a more concise manner.

All supported (and planned to be supported) GW5A series chips do not
support the 2: Read-before-Write write mode.
Here, we prohibit the generation of BSRAM with this mode.

This uses the environment variable `YOSYS_PLUGIN_PATH` to provide multiple colon-delimited search paths for native plugins in a similar manner to `PATH` for executables and `PYTHONPATH` for Python modules.
This addresses https://github.com/YosysHQ/yosys/issues/2545, allowing Yosys to be better packaged in non-FHS environments such as Nix.
