mem: Fix several issues in Scratch_Allocator
...
1. The size was being adjusted for the alignment which does not make any
sense without the context of the base pointer. Now we just add the
`alignment - 1` to the size if needed then adjust the pointer.
2. The root pointer of the last allocation is now stored in order to
make the free operation more useful (and to cover the right memory
region for ASan).
3. Resizing now only works on the last allocation instead of any address
in a valid range, which resulted in overwriting allocations that had
just been made.
4. `old_memory` is now re-poisoned entirely before the resized range is
returned with the new range unpoisoned. This will guarantee that
there are no unpoisoned gaps.
Fixes #2694

allocators
This adds various bindings to the asan runtime which can be used
to poison/unpoison memory handed out by various allocators. This
means we can catch use after free memory bugs when using operations
such as free_all during runtime.
Asan poisoning are added for the follow allocators in mem:
Arena (including temporary arenas)
Scratch
Stack
Small_Stack
Additionally a bug in the stack allocator was fixed to disallow freeing
in the middle of the stack (caught by the asan!).
I plan on adding support for all the allocators in core. This is just
a good starting point and were some of the easiest ones to implement
asan for.
