swiftlang#65253 (79e2697) made it so that the async and completion-handler variants of a member would both be matched by the same implementation, but the technique used composes poorly with typechecking work later in this series of commits. Reimplement it so that async variants are filtered out of `ObjCImplementationChecker::unmatchedRequirements` and then async candidates are compared against async alternatives later, during matching.
