4571e19387 heap: Add test to check that the corruption of free memory is detected
This commit extends the heap test set by adding a test to check corruption
detection in free memory block.

For each byte of the free block memory, the test changes the value of the byte,
call multi_heap_check(), make sure that the function returns 'corruption detected'
only when comprehensive poisoning is set, restore the good value of the byte, calls
multi_heap_check() again and make sure that it returns 'OK'.

4b7eb1792e Try to merge tail with next block when splitting
When splitting a memory block, check if the next block is free.
If it is, then just extend it upwards instead of creating a new block.
This fixes a bug where when shrinking existing allocations would result in irreversible free space fragmentation.

When testing on the host, test all the poisoning configurations.
