zephyr: Add support for split-heap.

Adds the ability to use PSRAM and non-contiguous memory.

Summary

I wanted to use PSRAM, this makes it possible and easy.
It also help support non-contiguous memory spaces, as this will not do any discrimination, it will be accepted as long as it's in memory space.

Testing

Tested with BL618, because rp2350 sadly doesnt have PSRAM support on zephyr yet.
