  Vulkan: Submit commands when Sync objects are initialized
  
  This CL calls ContextVk::flushImpl() after the sync object (VkEvent) has
  been created and initialized, so it has a valid Serial when it's waited
  on later.
  
  This change allows us to remove any tracking of pending sync objects,
  since all sync objects will be flushed and submitted by the end of
  SyncHelper::initialize().
  
  Bug: angleproject:6464
  Test: MultithreadingTest.CreateFenceThreadAClientWaitSyncThreadBDelayedFlush
