bors d488de82f3 Auto merge of #87587 - oli-obk:lazy_tait, r=spastorino
Various refactorings of the TAIT infrastructure

Before this PR we used to store the opaque type knowledge outside the `InferCtxt`, so it got recomputed on every opaque type instantiation.

I also removed a feature gate check that makes no sense in the planned lazy TAIT resolution scheme

Each commit passes all tests, so this PR is best reviewed commit by commit.
