`ac_structure` OK with some minor documentation (#183)

* Partial progress

* `func_809E7F94_jp` OK

* Do some more DMA functions

* Fix build

* Finally make `func_809E823C_jp` work properly

* Finish DMA functions

* Use ALIGN16

* Make the size for `mSc_secure_exchange_keep_bank` more obviously related to what follows

* Fix build after merge

* aSTR_setupActor_proc OK

* aSTR_init_clip_area OK

* Import data to C

* Lots of cleanup

* Use enum values in actors

* StructureActor-ify the structures

* Move `setupInfo_table` inside the function and name it

* Name `aSTR_get_pal_segment` from context clues

* Use all the names I can from DnM+

* Try (and fail) to import BSS into C

* Match bss

* Make bss sizes more "correct"

* Use ARRAY_COUNT to define DMA length

* A lot fewer hardcoded numbers

* Lots of misc cleanup

* A huge amount of names and cleanup

* Get this PR-ready

* Forgot some booleans

* Name a lot of stuff after digging into the object files

* Remove magic numbers for bss array size

* Respond to review
