Rollup merge of #33692 - nham:fix_E0207, r=GuillaumeGomez
Improve the long explanation of E0207. The previous explanation does not seem to explain what it means for an implementation parameter to be used or unused. The new explanation lists the three ways specific ways by which an impl parameter becomes constrained (taken from RFC 447). This also adds a link to RFC 447. The explanation has two different examples. The first is adapted from RFC 447, and shows an instance of E0207 on a impl for a type. The second one is a trait impl example adapted from issue #22834. Closes #33650 cc #32777 r? @GuillaumeGomez
