compile rust-anaylzer with `x check` if it's enabled

By default, `x check` doesn't compile the rust-analyzer. But when it's enabled in the config's tools section, there's no reason not to do it. This change allows `x check` to compile rust-analyzer if it's enabled in config's tools section.

Helps to rust-lang#115031
