Smart chunk culling for MC Windows 10 (RTX bug fix)

There are RTX resource packs in bedrock and what more important a lot of RTX issues. In this topic i want to mencsion problem of chunk culling. As everyone khows there is chunk culling in bedrock edeition (when player dont sees chunk it dissapears to increase performance), and this is a really helpfull feature for players on mobile or low-end PCs, but for those, who own high-end RTX-supporting PC this is a real problem, becouse chunk disappearence can cause "ghost-lighting" (especially when exploring caves). It happens becouse of emissive skybox.

I would like to suggest some ways of solwing this problem.

I. Placeholder texture. Instead of completly unrendering blocks their textures should be swapped to low-resolution placeholder texture, that obscures the light.

II. Smart culling. Culling now will not always be working, instead it will work only when device have run out of resources.

That's it! Thanks for reading and sorry for mistakes i might have made (English is not my native language)
