Separating moss from blocks into its own block similar to Glow Lichen

Rather than having to add new block variants that contain moss, which adds to development time and feature bloat.

It would be a good idea to separate the moss from mossy variants of various blocks, into its own block similar to Glow Lichen and Resin Clump. That way we would be able to have moss on wider variety of blocks.

This would however mean the removal of mossy variants of various blocks. This also includes nether mosses.

In addition, having moss as its own block would make it possible to introduce natural weathering mechanics where moss will grow from nowhere if it's in a damp or watery areas.
