ChiKyun Kim 1cee8de707 feat: Add Visual Studio 2022 VC++ project for C debugging
- Create complete VS2022 solution with 3 projects:
  * V2GDecoder: Main EXI decoder with debugging support
  * HexToBinary: Hex string to binary utility
  * HexDumpToBinary: Hex dump to binary utility

- Copy all source files locally for Windows compilation:
  * Added Windows compatibility for unistd.h, fstat, S_ISREG
  * Fixed VLA issues in EncoderChannel.c with macro definitions
  * Include all required modules: codec, iso1, iso2, din, appHandshake

- Build configuration:
  * Support Debug/Release x86/x64 configurations
  * Proper include directories and preprocessor definitions
  * Windows-specific compiler flags (_WIN32, __STDC_NO_VLA__)

- Verification:
  * Both test4.exi and test5.exi decode/encode perfectly
  * 100% binary compatibility: original ↔ XML ↔ reencoded
  * Ready for step-by-step debugging in Visual Studio
