Vulkan version 1.2 supports Workgroup execution model. Vulkan 1.3 introduced the LocalSizeId execution model and has been backported in the VK_KHR_maintenance4 extension. In future SPIR-V versions the Workgroup execution model will be deprecated. This PR checks the availability of VK_KHR_maintenance4 extension and when enabled compile the shaders towards Vulkan 1.3. This would automatically use the LocalSizeId execution model.
