Currently the `autocxx` generated code does not produce any code intelligence because `rust-analyzer` can't find the generated code since it's not in the workspace. Here, we detect `rust-analyzer` by checking for a `RUSTC_WRAPPER` environment variable containing `rust-analyzer` and changing (or avoid changing) the output directory accordingly. Closes #9654.
