Chalk PR that this brings in: rust-lang/chalk#821

Fixes #18083

cc @ShoyuVanilla I've seen you involved in other trait-upcasting-related issues, maybe this unblocks something else?

this adds a test asserting *incorrect* behavior that can be seen in
<rust-lang#18083>, and a test
asserting the *correct* behavior for the case of no super traits.
this brings in support from trait upcasting, yay!
(and as such fixes a test)

IIRC, I've been blocked by chalk on a couple of issues, but they are related to goal solving with associated types. But I'll check if there are any issues that can be solved with this chalk update. Thanks!
