move derive_smart_pointer into removed set
…to-coerce-referent, r=compiler-errors Rename macro `SmartPointer` to `CoercePointee` As per resolution rust-lang#129104 we will rename the macro to better reflect the technical specification of the feature and clarify the communication. - `SmartPointer` is renamed to `CoerceReferent` - `#[pointee]` attribute is renamed to `#[referent]` - `#![feature(derive_smart_pointer)]` gate is renamed to `#![feature(derive_coerce_referent)]`. - Any mention of `SmartPointer` in the file names are renamed accordingly. r? `@compiler-errors` cc `@nikomatsakis` `@Darksonn`

Cleanup: Move an impl-Trait check from AST validation to AST lowering
Namely the one that rejects `impl Trait` in qself types and non-final path segments.
There's no good reason to perform this during AST validation.
We have better infrastructure in place in the AST lowerer (`ImplTraitContext`).
This shaves off a lot of code.
We now lower `impl Trait` in bad positions to `{type error}` which allows us to
remove a special case from HIR ty lowering.
Coincidentally fixes rust-lang#126725. Well, it only *masks* it by passing `{type error}` to HIR analysis instead of a "bad" opaque. I was able to find a new reproducer for it. See the issue.
Clean up some comments on lint implementation This updates some doc comments that have gotten very out of date. Some of these macros were removed or renamed in rust-lang#57726 and rust-lang#104863 and others. Manual emitting of lints was significantly reworked when the `Diagnostic` infrastructure was added. Rather than try to replicate the high-level documentation, I added pointers to the rustc-dev-guide. I linkified some types so that if they are renamed/removed without updating the docs, it will break CI.
