Decompiles most FBDemo and transition functions (#92)

* Decompile fbdemo (transition) files

* run format.sh

* reformat vtx array, fill in a couple unk

* match TransitionTriforce_IsDone

* add VTX macro, add DW_ wrapping around triangle macros

* use new VTX macro, name graphic assets

* Naming updates

* pr updates

* naming updates

* remove symbols for COLOR_BUFFER, D_08000000, and D_09000000
