  Vulkan: Flush if sync object is pending during SyncVk::getStatus()
  
  When a glGetSynciv() is performed for GL_SYNC_STATUS, we should flush
  any pending commands if a sync object is pending a flush, since the
  caller is interested in the status of a fence. This will guarantee that
  the work is submitted to the hardware and eventually completes.
  
  This is accomplished by moving mSyncObjectPendingFlush from ContextVk to
  ShareGroupVk, so that any sync objects used by any contexts within the
  share group are submitted to hardware and the required work completes.
