Add clap_derive 4.5.32 benchmark

[Kobzol]

This PR adds a replacement for the clap benchmark. It contains only the clap_derive version from clap, because it is now a workspace. clap_derive is a proc-macro, we don't have that many of these in the benchmark suite.

I think this benchmark should be renamed from clap to clap_derive, and only the clap_derive crate should be included. (The latest version appears to be 4.5.32.) I think that would remove the need for the workspace selection?

[Kobzol]

That idea also crossed my mind, although the Cargo.toml of clap_derive uses some workspace configuration options, so I would need to modify it slightly. But I suppose that's not really a big issue. So if you're fine with that, I'll do it.

I would still keep the workspace selection logic in rustc-perf, it's quite useful for local benchmarking when you want to benchmark a workspace crate that is not in the main benchmark suite.

Replaced clap with clap_derive.
