[Python plugin]: Consider including a rust compiler by default

[lengau]

What needs to get done

Consider including a rust compiler as a build package/snap for the Python plugin. Likely, this would use the same logic as the existing rust plugin.

Why it needs to get done

A huge number of Python applications have rust dependencies at this point, using things like pydantic, pyre or cryptography. As such, it may be worth simply making a rust compiler a dependency of the Python plugin too.
