Due to the unusual (for Guix) compilation model used by
cargo-build-system, any phases or inputs added by a given library crate
need to be duplicated in all its dependents. This patchstack attempts to
solve this by allowing to propagate inputs, native-inputs and phases
across cargo-inputs edges in the dependency graph.
Apart from the build system work itself, I have included samples of the
cleanup they allow. Apart from being a good example, these are the
changes I have used to test the feature.

gnu: crates-io: Use propagated-inputs and propagated-native-inputs.
build-system/cargo: Add a propagated-phases argument.
gnu: crates-io: Use propagated-phases.
