Nicholas Nethercote c4a69d4712 Bring back enum DepKind. ...

It was removed in #115920 to enable it being moved to
`rustc_query_system`, a move that has recently been reversed. It's much
simpler as an enum.

Also:
- Remove the overly complicated `Debug` impl for `DepKind`.
- Remove the trivial `DepKind` associated constants (`NULL` et al.)
- Add an assertion to ensure that the number of `DepKinds` fits within a
  `u16`.
- Rename `DEP_KIND_VARIANTS` as `DEP_KIND_NUM_VARIANTS`, to make it
  clearer that it's a count, not a collection.
- Use `stringify!` in one place to make the code clearer.
