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 rust-lang/rust-clippy#8282 (comment) for context).
* Lint `match` constructions with tuples (as suggested at rust-lang/rust-clippy#8282 (comment))

Closes rust-lang#8282
