    evas common: disable thread_queue feature on win32.

    We have an issue that eina_thread_queue msg isn't delivered properly on win32.
    That occurs broken image drawing in case of non-smooth scaling.

    I disabled this feature on win32 because scale_sample_draw is gonna be rarely used
    since async rendering introduced.
