feat: add no-binary pypi-option

[thomas-maschler]

This PR implements the no-binary pypi-option to force Pixi to not use pre-built wheels for some or all dependencies (#3866).
This option is equivalent to uv's no-binary option

Usage

[dependencies]
libgdal = "==3.11.0"  # install GDAL binary from Conda

[pypi-dependencies]
rasterio = "==1.4.3"  # prebuild wheel ships with GDAL 3.9

[pypi-options]
no-binary = ["rasterio"]  # Rasterio will be built against Conda GDAL binaries

Note: This implementation works for me. Tested on Linux (debian/bullseye) and MacOS (M2 15.2). Check used GDAL version with:

python -c "import rasterio as rio; print(rio.__gdal_version__)"

I didn't add new logic to src/lock_file/satisfiability/mos.rs. I was unsure what to do there, and it seems to work just like that.

Thank you looks great, just two things:

• Can you add it the option to: schema/examples/valid/full.toml
• Can you add it beneath the: https://pixi.sh/latest/reference/pixi_manifest/#no-build section

Thanks!

@tdejager please take another look
