Include "stage" of dependency compilation

[Mark-Simulacrum]

Particularly in rust-lang/rust, it might be a bit confusing to see rustc_mir finishing before librustc (for example) so it'd be great to include e.g. (codegen) after the name of the crate, similar to how I believe we do so today for build scripts. Not sure if we have the relevant information in the place the progress bar is generated though

It would also be cool to have as an indicator for when the "check-like" part of the compiler is over, and maybe could be used to visually spot crates that take a disproportionate amount of time in either "half" of the compilation (before spending profiling efforts on any one crate).

Since this was created, we added --timings flag which reveals the split between the two sides of compilation.

btw I recommend people look at rust-lang/rust#24335 for more context.
