Vulkan: Add RefCountedEvent class and VkCmdSetEvent call This CL defines RefCountedEvent class that adds reference counting to VkEvent. CommandBufferHelper and ImageHelper each holds one reference count to the event. Every time an event is added to the command buffer, the corresponding RefCountedEvent will be added to the garbage list which tracks the GPU completion using ResourceUse. That event garbage's reference count will not decremented until GPU is finished, thus ensures we never destroy a VkEvent until GPU is completed. For images used by RenderPassCommands, As RenderPassCommandBufferHelper::imageRead and imageWrite get called, an event with that layout gets created and added to the image. That event is saved in RenderPassCommandBufferHelper::mRefCountedEvents and that VkCmdSetEvents calls are issued from RenderPassCommandBufferHelper::flushToPrimary(). For renderPass attachments, the events are created and added to image when attachment image gets finalized. For images used in OutsideRenderPassCommands, The events are inserted as needed as we generates commands that uses image. We do not wait until commands gets flushed to issue VkCmdSetEvent calls. A convenient function trackImageWithEvent() is added to create and setEvent and add event to image all in one call. You can add this call after the image operation whenever we think it benefits, which gives us better control. (Note: Even if forgot to insert the trackImageWithEvent call, it is still okay since every time barrier is inserted, the event gets released. Next time when we inserts barrier again we will fallback to pipelineBarrier since there is no event associated with it. But that is next CL's content). This CL only adds the VkCmdSetEvent call when feature flag is enabled. The feature flag is still disabled and no VkCmdWaitEvent is used in this CL (will be added in later CL).
