RP2040 fixes (#424)

Browse source 
* RP2040: malloc needs to be thread safe for FreeRTOS whether both cores are used or not

* RP2040: CMake file had broken left over test code

* RP2040: portIS_FREE_RTOS_CORE() returned an incorrect value prior to scheduler init when the application was compiled without multicore support

* RP2040: Bad initialization code was causing IRQs to get disabled before main() was called when using non static allocation
