[sanitizer] allocator: split the local cache class into two, one for 32-bit allocator and one for 64-bit one. NFC. The two imlementations will diverge in the following changes.

[sanitizer] use 32-bit offset instead of 64-bit pointers in the 64-bit allocator's transfer batches. This saves 2x memory for the transfer batches (up to ~1.5% overall in some cases)

[sanitizer] allocator: move TransferBatch into SizeClassAllocator64/SizeClassAllocator32 because we actually need different iplementations for the 64- and 32-bit case. NFC; the following patches will make the TransferBatch implementations differ
