FreeRTOS for the Renesas Demonstration kit (RDK) for the RX62N

Actually the head revision in Git, but effectively the same as v20221201 as far as the RX62N demo is concerned.

I was able to update the FreeRTOS source files to the head revision in Git (v2022120x) and build the project. I was also able to download the binary to the board and run it.

Thank you for reporting back.
