Regression in #117586

Opportunistically resolve region var in canonicalizer (instead of resolving root var) See comment in `compiler/rustc_type_ir/src/infcx.rs`. The **root** infer region for a given region vid may not actually be nameable from the universe of the original vid. That means that the assertion in the canonicalizer was too strict, since the `EagerResolver` that we use before canonicalizing is doing only as much resolving as it can. This replaces `resolve_lt_var` and `probe_lt_var` in the `rustc_type_ir` API with `opportunistic_resolve_lt_var`, which acts as you expect it should. I left a FIXME that complains about the inconsistency. This test is really gnarly, but I have no idea how to minimize it, since it seems to kind of just be coincidental that it triggered this issue. I hope the underlying root cause is easy enough to understand, though. r? `@lcnr` or `@aliemjay` Fixes rust-lang#118950
