Merge 15e49d444f into fdde91269b

This commit adds support for using pixi as a package manager alongside
Homebrew and MacPorts on macOS. When pixi is detected and Homebrew/MacPorts
are not available (or skipped), python-build will automatically use
dependencies from pixi's `python-deps` environment.

Key changes:
- Add `can_use_pixi()` and `pixi_env_prefix()` helper functions to detect
  and configure pixi environments
- Add `use_pixi_*()` functions for yaml, readline, ncurses, openssl, zlib,
  and tcl-tk to link against pixi-provided dependencies
- Support `PYTHON_BUILD_SKIP_PIXI` environment variable to disable pixi
- Support `PYTHON_BUILD_PIXI_ENV` to specify a custom pixi environment name
  (defaults to "python-deps")

The pixi integration follows the same pattern as Homebrew and MacPorts,
checking for package availability via `pixi global list` and using the
environment directory from `pixi info`.
