This implements Chilling Neigh, Grim Neigh, and both As One abilities.
Also separates the Embody Aspect ability into four for later when it's implemented, and adds the graphics for Ogerpon's Terastallized forms.
Mostly implements Gouging Fire, Raging Bolt, Iron Boulder, and Iron Crown. They still require shiny sprites and cries, and have placeholders for now. Galarian Mr. Mime also removed as a starter (evolve Mime Jr. instead).
Hydrapple and Archaludon are now able to be used. Dipplin also, as it was missing all it's graphics previously. Dragon Cheer is also in the TM pool now to accommodate this change.
