Refactored the build logic to improve build with freeRTOS and in VSCode

[Spider84]

• Removed colors from CMake output under VSCode (VSCode Output window can't show ASCI colors)
• Changed ${SDL2_LIBRARIES} to SDL2::SDL2 to fix SDL2main link error on Windows.
• freeRTOS build dependencies for Windows and Posix builds

Summary by cubic

Refactored the CMake build to improve FreeRTOS builds on Windows and Posix and make VSCode builds clearer. Also fixed SDL2 linking issues on Windows.

• Refactors

  • Detect VSCode and disable CMake color output for readable logs.
  • Select FreeRTOS port per platform: MSVC/MingW on Windows, GCC Posix otherwise.
  • Include the correct FreeRTOS port sources via FREERTOS_PORT_PATH.
  • Auto-set LV_USE_OS to FreeRTOS when FreeRTOS headers are present.
  • Guard main entry points: use freertos_main for FreeRTOS, main.c otherwise.
  • Link SDL via SDL2::SDL2 target instead of SDL2_LIBRARIES.

• Bug Fixes

  • Resolve SDL2main link error on Windows by linking to SDL2::SDL2.
