port 2A step 2: copy the 40250 header closure into the port mirror

76 closure headers (EterBase, EterLocale, EterPack, EterLib, GameLib, MilesLib,
EffectLib, SphereLib, EterImageLib) copied by the new port_copy.py (CP949->UTF-8,
LF, include-path case only); platform-class headers go to the mirror path too, as
the interface platform/ implements. Six manual `// PORT:` edits (Random, Singleton,
Pool, Stl, Utils, FlyTarget).

- common/D3D8Types.h: D3D8 value types with SDK values/layout, opaque COM interfaces
- common/shim/sdk (d3d8/d3dx8/mss) on every platform, common/shim/win32 off Windows
- Win32Types/Win32Crt: HRESULT, GUID, LARGE_INTEGER, LOGFONT/TEXTMETRIC, _atoi64,
  CRITICAL_SECTION on std::recursive_mutex
- header gate prepends each library's StdAfx.h (40250's precompiled header)

port_gate: macOS, Android, iOS, Windows (mingw) PASS; Linux BLOCKED (no toolchain).
ScriptLib/EterPythonLib/UserInterface wait for 2P (their StdAfx includes Python).
