Treat unstable lints as unknown #94274

This change causes unstable lints to be ignored if the unknown_lints
lint is allowed. To achieve this, it also changes lints to apply as soon
as they are processed. Previously, lints in the same set were processed
as a batch and then all simultaneously applied.

This change causes unstable lints to be ignored if the `unknown_lints`
lint is allowed. To achieve this, it also changes lints to apply as soon

This also affects the `non_exhaustive_omitted_patterns` and
`must_not_suspend` lints as they are not stable. This also changes the
diagnostic level to pull from `unknown_lints` instead of always being
allow or deny.
