Port fab59bbb

Original Commit Message:

    The previous implementation of MicrotaskQueue::RunMicrotasks() didn't
    support non-default MicrotaskQueue as RunMicrotasks builtin couldn't
    take a parameter.

    This CL updates the entry trampoline for RunMicrotasks builtin to pass
    a MicrotaskQueue parameter to support non-default one.
