Summary: Currently `TransferBatch` are located within the same memory regions as "regular" chunks. This is not ideal for security: they make for an interesting target to overwrite, and are not protected by the frontend (namely, Scudo). To solve this, we re-introduce `kUseSeparateSizeClassForBatch` for the 32-bit Primary allowing for `TransferBatch` to end up in their own memory region. Currently only Scudo would use this new feature, the default behavior remains unchanged. The separate `kBatchClassID` was used for a brief period of time previously but removed when the 64-bit ended up using the "free array".
