Porting guide for important files for FreeRTOS:
In sample root and "Application" folder we duplicated and modified important files:
sample root:
1. standalone.c. (for heap assignment)
2. wb_init.s. (for SWI handler, e. g., vTaskDelay)

"Application":
3. FreeRTOSConfig.h. (for mutex config)
4. GUI_X_FreeRTOS.c. (time related on FreeRTOS platform)

Please note that BSP emWin library is for non-OS ONLY, hence, please don't run emWin related on multiple tasks.
