Add support for multiple shadowcaster planes

Browse Source 
Extended ShadowcasterUpdater and shaders to handle multiple shadowcaster planes by introducing indexed properties and logic for two shadowcaster sets. Updated property names and shader logic to support per-index shadowcaster textures, colors, and brightness, enabling more flexible shadow casting in scenes.
