STM32H5 target has warning of the implicit declaration.

Describe the bug During the build of the STM32H503RB, the compiler warns the InitPlatform() and ExecPlatform() are implicitly declared in app_freertos..

The warning messages are shown below :

To Reproduce Build the Murasaki application with STM32H503RB.

Expected behavior Warnings should not be shown. To suppress them, the following code should be inserted to app_freertos.c by the installer.

#include "murasaki_platform.hpp"

Note that this may cause double including of the murasaki_platform.hpp in main.c with older MCU. But it is not problematic, actually.
