Rollup merge of #140236 - lcnr:normalizes-to-goals, r=compiler-errors
norm nested aliases before evaluating the parent goal

see the explanation of the underlying issue in tests/ui/traits/next-solver/normalize/eager-norm-pre-normalizes-to.rs.

This is also the cause of https://github.com/rust-lang/trait-system-refactor-initiative/issues/184, fixing the overflow errors with the new solver. I did not add any tests based on it directly as relying on that behavior to cause recursion limit shenanigans feels fragile. Thanks `@Nadrieril` for minimizing the issue [on zulip](https://rust-lang.zulipchat.com/#narrow/channel/364551-t-types.2Ftrait-system-refactor/topic/typenum.20.602.20.2F.201.60.20overflow.20error/with/513993621).

r? `@compiler-errors`
