Add better Farsight/Render Distance

I've been playing with the Farsight Mod for Java, and I noticed how well my PC ran even at nutso render distances. I feel like MC Bedrock should have a setting like this, like at far distances some blocks get merged into a lower res or each chunk turns into a one-color cube, that configures with render distance, so even players with an underpowered device can still see farther. It's also really annoying when you still see chunks just plop in through the fog, as it breaks the immersion. Other games do the farsight style thing, like Hytale, with a lower poly count at high render distances, but when Minecraft doesn't have it, it feels terribly unoptimized.
