Refactor render pipeline and resource management APIs

Split IFenceSynchronizer/IRenderSystem interfaces for clarity. Refactor D3D12GraphicsEngine to use IFenceSynchronizer. Update RenderGraph and context to use explicit resource manager/database/allocator references. Add multi-buffering methods to IRGBuilder (stub). Support history access for multi-frame resources. Remove legacy RenderPipelineBase; introduce IRenderPipelineSettings and sealed GhostRenderPipeline. Clean up resource aliasing and pool logic. Improve modularity and future extensibility.
