When in
constcontext (like array lengths) we erase all substs.Because of this, we used to emit spurious suggestions to restrict type
parameters when using associated types on them, even though that would
never work. Instead, we now signal
constcontexts when evaluatingtraits and emit a more accurate error.
Address the diagnostics part of #43408 and #61730.
