[ntsc-1.2] Decompile fault.c (#2046)

Browse source 
* wip decomp ntsc-1.2 fault.c

* more ntsc-1.2 fault.c

* decompiled fault_v1.c

* name fault_v1 functions, wip

* try to clean up build system (two versions of the fault system coexisting)

* cleanup

* cleanup2

* fix build gc-eu-mq-dbg

* match 2 more, ty anon

* matched

* review

* more review

* fixup spec

* `(uintptr_t)ptr op int` instead of `ptr op (type*)int`

* move fault.h out of global headers, properly include fault.h and versions.h

* compile all fault_*.c files regardless of version by overriding FAULT_VERSION

* n64 FaultMgr.framebuffer s32 -> u16*

* FaultMgr.framebuffer -> FaultMgr.fb

* make gc FaultMgr.fb u16* (yes, thats everything)

* bss

* fix Fault_Printf return type

* noop FaultDrawer_SetFontColor, FaultDrawer_SetCharPad in fault_n64

* fault_color_ stuff is only for fault_gc

* rm empty line in makefile

* I guess `D_80105A90_unknown` is `[sg]TotalAllocFailures`

* bss

* `Fault_WaitInput` -> `Fault_WaitForInput`

* use named fault funcs in pointers array

* FAULT_OOT{N64,GC} -> FAULT_{N64,GC}

* Apply suggestions from code review

* review, sync fault_{gc,n64}

* Apply `FPCSR_CE` suggestions from code review
