Create dedicated heap for supplicant operations. Currently, WPA supplicant uses the k_malloc, which is shared across various subsystems, and we cannot enforce a minimum availability. Using a dedicated HEAP that can be pre-allocated solves this by always having necessary memory .
Introduce an option for user to choose between dedicated heap and system heap.
