Data Compat for Gardens of the Dead, Undergarden, Unusual End & Deeper and Darker

[VoidLeech]

Adds/Expands data compat for the mods I add compat for in my treecutter PR:

• Gardens of the Dead
• Undergarden
• Unusual End
• Deeper and Darker
• Quark
  Some of these have some compat built-in themselves but not complete.

Consists of:

• Wood cutting recipes (GOTD, UG, DD)
• Flower milling recipes (all)
• Grass filling recipe (UG: deepturf)
• Ore crushing recipes (UG)
• Clay milling recipe (DD: sculk grime)
• Bucket emptying recipe (UG)
• Stone milling recipe (UG: depthrock -> pebbles (which are craftable into depthrock)
• Horse armor crushing recipe (UUE)
• Additions to Tags (fan_transparent, upright_on_belt, tree_attachments, modded_stripped_logs, modded_stripped_wood)

Concerns

• Echoes some concerns from Data Compat for the Aether & Major Addons #7084 regarding milling recipes for flowers that don't have a dye-crafting recipe in the base mod, choice of output dyes, or not having milling recipes for (e.g.) grasses that don't have any other outputs in their loot tables.
• Yes the blooming stem recipe produces 6 planks even though the stem isn't a full block. Crafting give 4 for which 6 is standard.
• Contains the same modFlower helper and DatagenFluidStack additions as that PR (same commits)
