Use an empty vendored file system in Ruff (#13436)

## Summary

This PR changes removes the typeshed stubs from the vendored file system
shipped with ruff
and instead ships an empty "typeshed".

Making the typeshed files optional required extracting the typshed files
into a new `ruff_vendored` crate. I do like this even if all our builds
always include typeshed because it means `red_knot_python_semantic`
contains less code that needs compiling.

This also allows us to use deflate because the compression algorithm
doesn't matter for an archive containing a single, empty file.

## Test Plan

`cargo test`

I verified with ` cargo tree -f "{p} {f}" -p <package> ` that:

* red_knot_wasm: enables `deflate` compression
* red_knot: enables `zstd` compression
* `ruff`: uses stored


I'm not quiet sure how to build the binary that maturin builds but
comparing the release artifact size with `strip = true` shows a `1.5MB`
size reduction
