This commit merges the logic used for opaque type type inference for impl Trait and non-impl Trait cases. This fixes an ICE where existential types used in the return types of functions would be allowed to have an out-of-scope generic type parameter.
…lper trait Before this change `SliceConcatExt` was an unstable extension trait with stable methods. It was in the libstd prelude, so that its methods could be used on the stable channel. This replaces it with inherent methods, which can be used without any addition to the prelude. Since the methods are stable and very generic (with for example a return type that depends on the types of parameters), an helper trait is still needed. But now that trait does not need to be in scope for the methods to be used. Removing this depedency on the libstd prelude allows the methods to be used in `#![no_std]` crate that use liballoc, which does not have its own implicitly-imported prelude.
Support `impl Trait` in inlined documentation `impl Trait` in argument position was not properly rendered when inlined from other crates. ([a live example on docs.rs](https://docs.rs/libp2p/0.8.1/libp2p/floodsub/struct.Floodsub.html#method.unsubscribe))  ↓
