single_match: Don't lint non-exhaustive matches; support tuples
`single_match` lint:
* Don't lint exhaustive enum patterns without a wild.
Rationale: The definition of the enum could be changed, so the user can get non-exhaustive match after applying the suggested lint (see https://github.com/rust-lang/rust-clippy/issues/8282#issuecomment-1013566068 for context).
* Lint `match` constructions with tuples (as suggested at https://github.com/rust-lang/rust-clippy/issues/8282#issuecomment-1015621148)
Closes#8282
