feat(buildPythonPackage): support new pyproject format

NixOS/nixpkgs#271597 implemented a new format for python packages that is starting to get traction in nixpkgs/unstable (soon to become NixOS 24.05).

That is a progress towards NixOS/nixpkgs#272178, which would be a massive improvement for dream2nix once completed.

This first step just makes sure that `buildPythonPackage` supports the new arguments properly. Without this change, many dream2nix python derivations fail to build on nixos-unstable right now.

Probably other python auto-builders should leverage these new options when available for the d2n user. That can be added later.
