Avoid searching for chunk sections that don't only have non empty blocks, but also non empty fluids

The logic here does not look correct for modded. Water and lava are not the only possible fluids.

I would suggest making the count generic and just counting non-empty fluidstates in the chunk section instead.

Since Fabric/Vanilla version of the method has the TagKey as a parameter, we would like to only check for the count of non-empty fluid states that have the same fluid TagKey to avoid unnecessary chunk section searches that do not have any fluid has the same TagKey as the parameter.

As for modded fluid/NeoForge version of the method, I will implement a counter for generic non-empty fluid states.

We can take fluid counts in a chunk section into account to
avoid unnecessary searches as we were only checking for non
empty blocks.
