This removes an unnecessary coupling between ExecutorProcessControl and DylibManager, allowing clients to select DylibManager implementations independently. To simplify the transition, the ExecutorProcessControl::createDefaultJITDylib method will return an instance of whatever DylibManager the ExecutorProcessControl implementation had been using previously.
