Fix CMake build for RP2040 (FreeRTOS#1197)

Add public dependency to hardware_sync because portable\ThirdParty\GCC\RP2040\include\portmacro.h exposes include "hardware/sync.h" to FreeRTOS.h which is PUBLIC.

Add private dependency to pico_multicore because of usage prvFIFOInterruptHandler() and sio_hw in portable/ThirdParty/GCC/RP2040/port.c.
