Render correct model for TCG Keys when they're not shuffled and unique key models are enabled

[Echopixel]

Fixes #2464 - Adding a check to also lookup the model inside the chest if CUSTOM_KEY_MODELS is true seems to be all this needed. I tested the case where they're not shuffled with unique key models enabled and it looks correct now.

One more thing to test: How does it behave when opening the rupee chest?

Nice catch, yeah, it's still not quite right. Instead of the model it renders a basic key sprite when you grab the loser chest

Will investigate more for that unless anyone already knows what handles that rendering

So I poked at it a little more knowing I'd probably get stuck, but looking through the decomp I think this function in z_en_ex_item.c where it checks if EXITEM_SMALL_KEY_CHEST and if so calls EnExItem_DrawKey(this, play, 0); is where this last render is happening.

Also seems like the chest game in en_changer is the only place that uses that ex item type to determine to do this specific texture draw, so maybe if we can replace that with a draw_model call if it's EXITEM_SMALL_KEY_CHEST && CUSTOM_KEY_MODELS might work or override the EnExItem_DrawKey function and call that if it's chest game chest key chest and custom key models is enabled. Granted, I don't know how to do any of that yet since I'm trying to learn, so probably need a SME to assist assuming this is even the right direction to go.
