Short summary

Swithc from mallocallocator to kmalloc allocated in Zephyr

Steps to reproduce

Swithc from mallocallocator to kmalloc allocated in Zephyr. This will allow us to have a real picute of the RAM usage in our system. when you are building it says we are using 75% of RAM but really what is happening is its not using kmalloc and so we dont know what is being done by malloc

You may have to override the allocator class, but not sure on the implementation.
