This PR constrains the support added for handling unevaluated consts in polymorphization (introduced in #75260) by:
Self
as this ensuresT
is used in constants of the form<Self as Foo<T>>
.Due to an oversight on my part, when landing #75260 and #75255, some tests started failing when polymorphization was enabled that I didn't notice until after landing - this PR fixes the regressions from #75260.
