Update rendering architecture and resource management

Added a new `Ref<T>` struct for reference semantics.
Added the `RenderGraph` system for managing rendering passes.
Added the `RenderTexture` class for encapsulating GPU resources.
Added `GraphicsBuffer` class for effective GPU resource management.
Changed `CommandList` methods from public to internal for visibility control.
Changed `IRenderPass` interface from internal to public for accessibility.
Changed `GetData<T>()` in `ComponentObject.cs` to return `CompRef<T>`.
Changed `GetComponent<T>()` in `EntityManager.cs` to return `CompRef<T>`.
Changed `GetSingleton<T>()` in `World.cs` to use `CompRef<T>`.
Changed `IQueryTypeParameter` to use `CompRef<T>` for consistency.
Changed `QueryItem<T0>` and related structs to use `CompRef<T>`.
Changed `Material` class to support bindless textures.
Changed `Shader` class to support bindless rendering.
Changed `Mesh` class to support bindless vertex and index buffer access.
Updated documentation to reflect the new bindless rendering architecture.
