Warn when a crate could unexpectedly pull in libstd.
Example on Polkadot-SDK:

Since these crate do have both:
#![cfg_attr(not(feature = "std"), no_std)]and#![cfg(feature = "runtime-benchmarks")]which conditionally disables the nostd attribute.Note that this is just a warning for now. Could be made into an additional lint (plus failure condition) in the future.
