[Orc] Allow OrcGenericABI variant of LazyCallThroughManager

Apply the way createLocalIndirectStubsManagerBuilder() deals with unsupported achritectures to createLocalLazyCallThroughManager(). The returned call-through manager is dysfunctional: It runs into an unreachable as soon as a lazy JIT attempts to use it. However, this results in broader platform support for lli in default (greedy) ORC mode where no lazy materialization is required.
