feat: Implement render graph support in Vulkan backend

- Added RecordRenderGraph method to IRenderCommandService and its implementation in RenderCommandService.
- Updated VulkanGraphicsBackend to handle render graph definitions and record commands accordingly.
- Introduced GetDepthFormat method in ISwapchainService to retrieve depth buffer format.
- Enhanced VulkanGraphicsBackend with methods to set render graph definitions and manage render graph resources.
- Added RenderGraphImage structure to manage render targets and depth targets within the render graph.
- Updated interfaces and services to accommodate new render graph functionality, including descriptor set layout retrieval in IPipelineService.
