6ad2757b - [Concurrency] Use completion/completionHandler parameter names for async import

[Concurrency] Use completion/completionHandler parameter names for async import Extend the check for completion handler parameters to also consider the name of the parameter (not its argument label). If it's `completion` or `completionHandler`, we have a completion handler. This extends our API coverage for importing Objective-C methods with completion handlers as 'async'.
