  [TSan][Darwin] Fix shadow mapping for iOS simulator on Apple Silicon

With the introduction of Apple Silicon `defined(__aarch64__)` is not a
reliable way to check for the platform anymore.

We want to use the "normal" `Mapping48AddressSpace` mapping everywhere
except devices, including the iOS simulators on AS.
