Various fixes/matches

- Matched all remaining functions in `__osMalloc.c`, 2 functions in `code_8007BF90.c`, 1 in `code_800A9F30.c`, 2 in `fault.c`, 1 in `fault_drawer.c`, 1 in `gfxprint.c`, 2 in `z_camera.c`
-  Improved most other remaining non matchings to ensure they are actually equivalent and to get them closer to matching
- Added a `alloc.h` header file in the process of working on `fault.c` non matchings
- Decompiled `padmgr.c` data/bss in order to improve padmgr non matchings
- Removed unused `z_en_wallmas.c` data files
- Moved functions confirmed to be in `z_cheap_proc.c` to their own file with that name
