This change updates the current tiled rendering APIs to use the full RTX
tiled rendering feature, allowing for higher quality RGB renders and
support of additional annotators, including semantic segmentation,
instance segmentation, normals, and motion vectors.

This change also aligns output dimensions across TiledCamera, Camera,
and RayCasterCamera classes. All single-channel outputs will now have
dimension (H, W, C). Camera class now outputs RGB data with shape (H, W,
3).
