chore: upgrade FreeRTOS to v2 (CMSIS-RTOS_V2), update CubeMX project config

- Remove CMSIS-RTOS v1 (cmsis_os.h/cmsis_os.c), add CMSIS-RTOS v2 (cmsis_os2.c/freertos_os2.h/mpool.h)
- Update FreeRTOS kernel, port, and headers to match v2 integration
- Remove unused heap implementations, keep heap_4
- Update CubeMX project config (.mxproject, .ioc, CMakeLists.txt)
- Update FreeRTOSConfig.h, freertos.c, main.c, stm32h7xx_it.c
- Update application modules (master_machine, dmmotor)
- Add CMSIS-RTOS2 headers, mpu_syscall_numbers.h, newlib/picolibc support
