Potted mystical/special flowers and mushrooms

All (small) mystical flowers, glimmering flowers, shimmering mushrooms, motif flowers, and special flowers (generating, functional, misc) can be put into a flower pot.

- defined potted versions of all mystical, glimmering, motif, and special flowers, and shimmering mushrooms
- added datagen for potted flower content (models, block states, loot tables, flower pot tag)
- added translation keys for new potted flower/mushroom blocks
- compacted color block registration logic a bit
- special flower pot plant registration logic for Forge
