Use drmSyncobjSignal to signal out_syncobjs when a GPU job submission ends in the simulator. With this, we can enable multisync support in the simulator and keep the multisync approach to process fence by submitting a serialized no-op job that adds the fence to the array of out syncobjs, i.e. syncobjs to be signaled in the kernel when a job completes (job post deps).
