[9.x] Release lock for job implementing ShouldBeUnique that is disp…

…atched `afterResponse()` (laravel#46806)

* failing test

* rely on PendingDispatch@afterResponse so that ShouldBeUnique is checked

* modifications to failing test

* move lock/middleware handling to CallQueuedHandler@handle()

* use CallQueuedHandler@handle if job employs InteractsWithQueue

* style

* revert changes to CallQueuedHandler & PendingDispatch

* switch Bus\Dispatcher@dispatchAfterResponse to rely on Dispatcher@dispatchSync()

* add `dispatchAfterResponse` test
