Freestanding Items (#72)

* Bring in beginning of modified work of model drawing.

Still tons to do, but at least this is a starting point.

* Port OoT3DR functions for model management

* Add in some matrices commands so we can properly flip drawn objects.

Add in CMB files for zelda2keep.

* Include model scale, and bool to flip object if necessary in item table.

* Set correct mesh for rupees

* Adjust player struct and include En_Item00

* Add functions to spawn objects

* Adjust context to properly align with object_context.

Update models with debug.

Adjust item table for adult/giant wallets.

* Update item table. Now compiles. Need to double check item values but should work.

TODO: Implement Extended Object Context

TODO: Fix loaded models not scaling/positioning properly.

* Add in some TODOs for what is still needed for extended object info.

* Include Object function calls.

Create IsLoaded as we do not have a built-in function from game. This may be due to in-lining.

* Move object spawn and extended objects to own files.

* Include rough layout for spawning into rExtendedContext.

Still needs some work as we're still crashing.

* Extended Object now properly spawning in items.

* Properly zero out extended object context.

* Models are now placing properly, but rotation is still failing.

Fix crash for intro scene with PoH on clock tower.

* Zora mask is now drawing properly.

* Overhaul of custom extended context. Things now properly destroy.

* Mass update item scalings

Still need to find remains IDs and a few other things/test all items.

* Rough in dmchar05 overrides.

Update models in item table.

Update todo models in item table.

* More model update, stubbing in saModel2 calls.

* Fix progressive models for bomb bag item get.

More work on models.

* Skeleton animation not spawning twice.

* Revert 17C spawn.

Fix dual model spawning by adjusting the storedObjectId to not revert. Thanks Freddy!!

* Comment out animiation texspawn for now since we don't know how it works.

* Finish testing models.

Rough in DMChar_05, animations and few other things still needed.

Add Item_B_heart calls - free standing containers now draw proper items.

Add small debug text to avoid race condition on gold dust spawning?

TODO: Refactor float sizes as they are incorrect.

* Finish rescaling items.

* Begin work on Dm_Hina models.

Start attempting to override the remains that sit in the portal.

Everything else seems to be working as intended.

* Linter.

* Update to begin work on Dm_Hina overrides.

* Bring in debug tooling to move the actors xyz coords.

Comment out En_Dina for now as we can continue to work on it later.

* Linter
