DavidandClaude Fable 5.1 d991cdccf9 feat(libSceAmpr): implement the std::_Pad thread launch helpers
Implement _ZNSt4_PadC2Ev, _ZNSt4_PadD2Ev, _ZNSt4_Pad7_LaunchEPP7pthread
and _ZNSt4_Pad8_ReleaseEv, which Deathloop (PPSA01670) and Minecraft
Legends (PPSA05510) import from libSceAmpr for the std::thread launch path.

The algorithm and object layout follow Dinkumware V6.00 thr/xthread and
thr/threadcall.cpp of Visual C++ 2013 (ganboing/crt.vc12 f1d47126): a
vtable pointer whose first slot is the pure virtual _Go(), then the
condition and mutex handles and bool _Started (0x8, 0x10, 0x18), with the
console's pointer-to-slot handles of libc Threads.cpp (#3079). The pad
uses libc's _Cnd_*/_Mtx_* exports, starts the guest thread with
pthread_create and an entry that calls _Go() and returns its result as
the exit code, as _Call_func does. The unverified layout, thread
attributes and error reporting are recorded in TechnicalDebt.md.
