[Sanitizer][Darwin] Add interceptor for malloc_zone_from_ptr
Ensure that malloc_default_zone and malloc_zone_from_ptr return the
sanitizer-installed malloc zone even when MallocStackLogging (MSL) is
requested. This prevents crashes in certain situations. Note that the
sanitizers and MSL cannot be used together. If both are enabled, MSL
functionality is essentially deactivated since it only hooks the default
allocator which is replaced by a custom sanitizer allocator.
