Give impl Trait in a const fn its own feature gate

[ecstatic-morse]

...previously it was gated under #![feature(const_fn)].

I think we actually want to do this in all const-contexts? If so, this should be #![feature(const_impl_trait)] instead. I don't think there's any way to make use of impl Trait within a const initializer.

Yea I think this should just apply to all const contexts
