Rollup merge of #147713 - cjgillot:where-cfg, r=fmease
Retire ast::TyAliasWhereClauses.

`ast::TyAliasWhereClauses` is a tentative to avoid forgetting predicates when manipulating the AST.
It is incompatible with `cfg` attributes on where clauses.

This PR uses a regular `WhereClause` for the "second" clause.
