Auto merge of #118725 - lcnr:normalizes-to-projection-split-3, r=BoxyUwU

Browse source 
split `NormalizesTo` out of `Projection` 3

third attempt at #112658. Rebasing #116262 is very annoying, so I am doing it again from scratch. We should now be able to merge it without regressing anything as we handle occurs check failures involving aliases correctly since #117088.
