This PR implements #115590, which supports #[cfg] attributes in where clauses.

The biggest change is, that it adds AttrsVec and NodeId to the ast::WherePredicate and HirId to the hir::WherePredicate.

Thanks @frank-king for the work. I haven't looked deeply into the parser code yet, I need to familiarize myself with it first.

Refactor `where` predicates, and reserve for attributes support

Refactor `WherePredicate` to `WherePredicateKind`, and reserve for attributes support in `where` predicates.

This is a part of rust-lang#115590 and is split from rust-lang#132388.
