RISC-V: fix xTaskReturnAddress type

Browse source 
xTaskReturnAddress holds a [function] pointer, never an integer address.
Use a proper exclusive function pointer type for this variable.
Furthermore, use NULL instead of 0 for an invalid function pointer value

This typedef could be made more generic for FreeRTOS-Kernel and not
just for RISC-V; vApplicationTaskExit used to be declared/defined in
previous versions and ideally could just be brought back.
