When stack check is enabled, certain functions (sometimes placed in RAM) are being decorated with stack guards and a call to __stask_chk_fail() in case ofr stack corruption. For this reason, __stack_chk_fail() must be placed in RAM too. Add stack check config in heap tests on all targets to find eventual flash to RAM calls due to stack checks when running callgraph_check.py
