Fix type resolution of associated const equality bounds (take 2)

Instead of trying to re-resolve the type of assoc const bindings inside the `type_of` query impl in an incomplete manner, transfer the already (correctly) resolved type from `add_predicates_for_ast_type_binding` to `type_of`/`anon_type_of` through query feeding.

Together with rust-lang#118668 (merged) and rust-lang#121258, this supersedes rust-lang#118360.
Fixes rust-lang#118040.

Reject overly generic assoc const binding types

Split off from rust-lang#119385 to make rust-lang#119385 easier to review.

---

In the *instantiated* type of assoc const bindings

1. reject **early-bound generic params**
   * Provide a rich error message instead of ICE'ing ([rust-lang#108271](rust-lang#108271)).
   * This is a temporary and semi-artificial restriction until the arrival of *generic const generics*.
   * It's quite possible that rustc could already perfectly support this subset of generic const generics if we just removed some checks (some `.no_bound_vars().expect(…)`) but even if that was the case, I'd rather gate it behind a new feature flag. Reporting an error instead of ICE'ing is a good first step towards an eventual feature gate error.
2. reject **escaping late-bound generic params**
   * They lead to ICEs before & I'm pretty sure that they remain incorrect even in a world with *generic const generics*
