lots of AreaObj.* functions

[whaleymar]

pasted PR comment from the other repo:

This covers

• Reversed AreaObjDirector's methods and fixed some errors in its header
• AreaObjFactory header + reversed both methods
• Headers for AreaObjMtxConnecter and AreaObjMtxConnecterHolder
• 2 inlined functions in Factory to get AreaObj + AreaObjDirector stuff matching
• Headers for area objects used in the factory (includes TrafficArea, CameraStartParam, SeBarrierArea, SePlayArea, ViewCtrlArea, BirdGatheringSpotArea, ExtForceArea, ForceRecoveryKidsArea, MoveArea2D, NpcForceMaterialCodeArea, RouteGuideArea, and StainArea)
• ProjectAreaFactory header and a non-matching constructor

Things to sanity check:

• AreaObjDirector::getAreaObjGroup did not match when using the inlined _getAreaObjGroup. Instead, it only matches when I paste the exact same code into the public method. Inlining the binary search was necessary for several functions to match, but having 2 identical functions feels wrong.
• I don't know if I defined BirdGatheringSpotArea::AreaClippingInfo in the right spot

I'll deal with the linting stuff later I'm going to bed

Alright, I'll review when the linter is (mostly) fixed.
