Add a test to prove that hardened_malloc handles too-large-to-be-true allocations
...
This pattern, used by https://github.com/kaist-hacking/HardsHeap ,
uncovered bugs in other memory allocators.

malloc_usable_size: clean abort on invalid region
...
It's the region pointer that can be NULL here, and p was checked at the
beginning of the function. Also fix the test accordingly.

increase size for eight_byte_overflow_large test
...
This was not working as expected due to CONFIG_EXTENDED_SIZE_CLASSES
resulting in 128k being a slab allocation size class. The addition of
padding for the canary pushes it into the next size class, resulting in
this writing over size class rounding padding rather than this actually
being an overflow as intended.
