Increase grass rendering distance

[Xenius97]

This PR increases the grass rendering distance.
This is only one part of fully implementing the idea in #3842.
The problem is that even if we increase the view distance, it’s simply not enough. By default, the grass buffer is limited to 32, and to exceed this limit, the TriPlantBuffer would also need to be rewritten. I’m not that deep into it yet, but the view-distance increase works on its own, so if someone wants to take it further, they only need to handle increasing the grass buffer.

getGrassDrawDistance

closeDistance, farDistance = getGrassDrawDistance()

setGrassDrawDistance

bool = setGrassDrawDistance(closeDistance, farDistance)

resetGrassDrawDistance

bool = resetGrassDrawDistance()
