stabilize debug_non_exhaustive

tracking issue: https://github.com/rust-lang/rust/issues/67364

but it is still an open question whether the other `Debug*` struct's should have a similar method. I would guess that would best be put underneath a new feature gate, as this one seems uncontroversial enough to stabilize as is
