feat(rust/drivers): adbc driver for datafusion

[tokoko]

Fixes #2263

An initial driver implementation for datafusion:

• bunch of todos everywhere
• options are not supported
• get_objects ignores filters
• get_objects takes depth into account, but only when returning results, not for info retrieval
• minimal testing

P.S. I'm not much of a rust person, so I'd appreciate any kind of pointers

To fix the failing CI job we need to install protoc (required by the substrait crate):

You could add

- name: Install Protoc
  uses: arduino/setup-protoc@v3
  with:
    repo-token: ${{ secrets.GITHUB_TOKEN }}

as a step after https://github.com/apache/arrow-adbc/blob/4639ca8ba98a4a8e91ad1e5dac971dcb6835666d/.github/workflows/rust.yml#L68-L72.

@mbrobbel thanks, got everything green. I had to temporarily add #![allow(refining_impl_trait)] to lib.rs, couldn't get unimplemented methods that return Result<impl RecordBatchReader + Send> to pass clippy checks otherwise.

Let's merge this as a start. Thanks @tokoko @eitsupi!
