Angle cleanup - macros names (#1193)

Browse source 
* Move binang utility macros out of angle conversion macros block

* `BINANG_TO_DEGF` -> `BINANG_TO_DEG_ALT` (it may even be warranted to name it _approx instead of _alt, unsure)

* Add `BINANG_TO_DEG` (unused by oot) (for completeness)

* `DEGF_TO_BINANG` -> `DEG_TO_BINANG_ALT` (again may even be _approx, or maybe _cam)

* Add `DEG_TO_BINANG` (unused by oot) (for completeness)

* `RADF_TO_BINANG` -> `RAD_TO_BINANG`

* `RADF_TO_DEGF` -> `RAD_TO_DEG`

* Cleanup argument names in angle conversion macros

* Format for angle macros changes

* Run formatter

* Move `DEG_TO_BINANG_ALT`, `BINANG_TO_DEG_ALT` to z64camera.h

* Remove `DEG_TO_BINANG`, `BINANG_TO_DEG`

* Remove `_ALT` from `DEG_TO_BINANG`, `BINANG_TO_DEG`

* Add comment about inaccuracy near `DEG_TO_BINANG`, `BINANG_TO_DEG`

* run formatter

* `CAM_` prefix on `DEG_TO_BINANG`, `BINANG_TO_DEG` macros

* Revert "Remove `DEG_TO_BINANG`, `BINANG_TO_DEG`"
