Implement segmentable blocks (leaf litter, pink petals, wildflower)

[colonthreeing]

Leaf litter and similar blocks are implemented by this pr, as well as the function can_be_replaced (from vanilla's canBeReplaced in blockbehaviour.java line 831)

in specific:

• implemented placement rules (rotational placing, increasing stack count when clicked on or when placed in the same block)
  • behaviours are abstracted into a new module called segmentable_blocks matching vanilla.
• can_be_replaced function implemented on the block behaviour trait, still backs up to the config value but is replaceable.
• • needed for this pr specifically because all of these blocks override the behaviour.
• also makes them break when they are not supported and drop the correct material
• bonemealing works
  • bonemeal adds segments til it reaches the max, then creates an item
