Vulkan: Use StoreOp_None_QCOM for read only depth stencil buffer For read only depth stencil buffers, there is no need to store depth or stencil value. But we can not use DontCare for storeOp because vulkan core spec says DontCare indicates data is undefined after this. VK_QCOM_render_pass_store_ops extension introduces a new store op that will leave data defined but skip the store. This CL utilize this if the extension is available.
