We add a mechanism to install Python packages from (platform-independent) wheels instead of from source distributions.

This will allow us to make packages such as furo and jupyterlab standard. Currently they are pip packages, as they need internet connectivity to get Javascript packages (via nodeenv).

Here we make furo a standard wheel package. This is for #33833.

Depends on #34421
