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?

ARMv6K Horizon OS has_thread_local support

Being an ARM target, it has always had built-in support for `#[thread_local]`. This PR comes in just now because we were testing `std::thread` support with `thread_local_dtor`s. This will hopefully be the last PR for the target specification, unless anymore features will be needed as time goes on.
