Update clap to 4.5.36

[Kobzol]

This PR updates the clap benchmark to 4.5.36. Clap is now just a workspace where the root crate only contains documentation, so I benchmark the clap_derive crate, which has no local dependencies, so rustc-perf can deal with it. I added support for selecting a workspace package to rustc-perf to support this, that was easy enough.

clap_derive is a proc-macro, we don't have that many of these in the benchmark suite.
