resolve: Feed the `def_kind` query immediately on `DefId` creation

Before this PR the def kind query required building HIR for no good reason, with this PR def kinds are instead assigned immediately when `DefId`s are created.

Some PRs previously refactored things to make all def kinds to be available early enough - https://github.com/rust-lang/rust/pull/118250, https://github.com/rust-lang/rust/pull/118272, https://github.com/rust-lang/rust/pull/118311.
