Some of the ARC platforms aren't consistent between kconfig and their
linker scripts as to the size of memory, add a special case.

The renode emulator is REALLY slow on this test, what completes in 20
seconds on qemu takes 4-10 minutes on renode. That's causing trouble
in CI.
And this is a CPU-bound unit test of library code, where we have
coverage for riscv32 via qemu anyway. There's no value to having
better platform emulation here.

CONFIG_SRAM_SIZE is a kconfig value, which is an int (units of kb),
but when doing math on it to produce a memory buffer size needs to be
done in size_t precision otherwise we could overflow on 64 bit
platforms with >4G memory.

Use the white box validation and test rig added as part of the
sys_heap work. Add a layer that puts hashed cookies into the blocks
to detect corruption, check the validity state after every operation,
and enumerate a few different usage patterns:
+ Small heap, "real world" allocation where the heap is about half
full and most allocations succeed.
+ Small heap, "fragmentation runaway" scenario where most allocations
start failing, but the heap must remain consistent.
+ Big heap. We can't test this with the same exhaustive coverage
(many re/allocations for every byte of storage) for performance
reasons, but we do what we can.
