Add missing libc.prx symbols required by Unity IL2CPP runtime:
- Implement _Dtest double classification in Math.cpp
- Implement _Inf double constant in Math.cpp
- Implement sceLibcBacktraceGetBufferSize and sceLibcBacktraceSelf in Backtrace.cpp
- Implement _Cnd_signal in Threads.cpp
- Implement _ZNSt8ios_base7_AddstdEPS_ in RuntimeSupport.cpp
- Implement __pointer_type_info and __function_type_info vtables in TypeInfo.cpp
- Remove duplicate stubs from libSceAmpr/Export.cpp
- Add unit tests in GuestMath.cpp and GuestLibcThreads.cpp
- Document unverified behaviors in docs/dev/debt/libc.md
Deathloop (PPSA01670), Minecraft Legends (PPSA05510) and GTA III
Definitive Edition import both from libSceAmpr. They take a pointer to
the handle slot and act on the conditions created by the libc _Cnd_init:
_Cnd_signal wakes one waiter through a libc helper, _Cnd_init_with_name
is _Cnd_init with the name ignored. _Thrd_id still throws.
