Add heights and weights for most new Pokémon.

Missing: Aromatisse, Large Gourgeist, most Mega Evolutions.
Swap the order of Average and Small Pumpkaboo/Gourgeist.

Apparently the order column was one off starting after Arceus,
presumably from when I accidentally left Fairy Arceus as a second
default.
Belatedly commit the new item categories I added.
