esp_system: fix placement of __stack_chk_fail from flash to RAM

Browse Source 
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
