◆ MergeSubpassDependencies()

void AZ::Vulkan::RenderPass::Descriptor::MergeSubpassDependencies ( )

Necessary to avoid validation errors when Vulkan compares the VkRenderPass of the PipelineStateObject vs the VkRenderPass of the VkCmdBeginRenderPass. Even if the subpass dependencies are identical but they differ in order, it'd trigger validation errors. To make the order irrelevant, the solution is to merge the bitflags.
