Rollup merge of #93469 - compiler-errors:issue-93450, r=estebank
Skip pointing out ambiguous impls in alloc/std crates too in inference errors

This generalizes the logic in `annotate_source_of_ambiguity` to skip printing ambiguity errors traits in `alloc` and `std` as well, not just `core`.

While this does spot-fix the issue mentioned below, it would be nicer to generalize this logic, for example to detect when the trait predicate's `self_ty` has any numerical inference variables. Is it worthwhile to scrap this solution for one like that?

Fixes #93450
