Turn feature-gate table into a query so it is covered by dependency tracking.

Turn access to feature gates into a query so we handle them correctly during incremental compilation.

Features are still available via `Session` through `features_untracked()`. I wish we had a better way of hiding untracked information. It would be great if we could remove the `sess` field from `TyCtxt`.

Fixes rust-lang#47003.
