Auto merge of #103279 - compiler-errors:normalize-hack-back, r=lcnr

Add eval hack in `super_relate_consts` back

Partially reverts 01adb7e98d5656c06497f33dd2747df144e78356.

This extra eval call *still* needs to happen, for example, in `normalize_param_env_or_error` when a param-env predicate has an unnormalized constant, since the param-env candidates never get normalized during candidate assembly (everywhere else we can assume that they are normalized fully).

r? `@lcnr,` though I feel like I've assigned quite a few PRs to you in the last few days, so feel free to reassign to someone else familiar with this code if you're busy!

cc #103243 (fixes the issue, but don't want to auto-close that until a backport is performed).
