mm/slab: use stride to access slabobj_ext
Use a configurable stride value when accessing slab object extension
metadata instead of assuming a fixed sizeof(struct slabobj_ext).
Store stride value in free bits of slab->counters field. This allows
for flexibility in cases where the extension is embedded within
slab objects.
Since these free bits exist only on 64-bit, any future optimizations
that need to change stride value cannot be enabled on 32-bit architectures.
