[Stride] Custom present call

[tebjan]

PR Details

Description

This PR introduces the IPresentCallIntercept interface, which allows users to manage the present call of the GameWindowRenderer. This is useful where an alternative present method is required.

A use case is NVIDIA Quadro Sync, which has a dedicated Present method in NvApi that works with Quadro sync groups and sync barriers.

Additionally, this PR adds a hidden output pin to GameWindow and SceneWindow, outputting the GameWindowRenderer to set the present intercept and retrieve the swap chain used for the custom present.

Motivation and Context

This change is necessary to enable proper synchronization with NVIDIA Quadro Sync groups and sync barriers.

How about changing the interface to void Present(GraphicsPresenter presenter) and passing the interceptor as input instead of output? You could now build your custom NvQuadroSyncPresentInterceptor node and connect it from the top to the RenderWindow or SceneWindow. It would feel a little more guided to me - getting the object I need to deal with passed to me, instead of having to know I need to take it from somewhere.

Thanks for the feedback, connecting the node at the top to an input pin works well, I've changed the structure accordingly.
