Rollup merge of #57502 - nikomatsakis:fix-trait-alias-1b, r=nikomatsakis

make trait-aliases work across crates

This is rebase of a small part of @alexreg's PR #55994. It focuses just on the changes that integrate trait aliases properly into crate metadata, excluding the stylistic edits and the trait objects.

The stylistic edits I also rebased and can open a separate PR.

The trait object stuff I found challenging and decided it basically needed to be reimplemented. For now I've excluded it.

Since this is really @alexreg's work (I really just rebased) I am going to make it r=me once it is working.

Fixes #56488.
Fixes #57023.
