Some biome_lib replacement experiments

[Niklp09]

These are only some experiments so far, do not expect too much. Some parts of the code are based on wsor's moretrees anti biome_lib PR:tm: (https://github.com/mt-mods/moretrees/pull/11)

At some point, we should think about placing as many plants as possible with schematics and without on_generated call.

Warning, some plants still spawn in wrong biomes

Is anyone familiar with noise_params? If yes, please take a look at https://github.com/Niklp09/plantlife_modpack/blob/bl/plantlife_lib/util.lua#L26. I took the param generator from biome_lib, but it doesn't seem to work properly with many plants. Perhaps someone has an idea how I can improve it.
