[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

[sanitizer] allocator: introduce kUseSeparateSizeClassForBatch (false by default). When true, it will cause all TransferBatches to be allocated on a separate dedicated size class, which improves security and may potentially simplify memory reclamation. However in the current state this may cause up to 3% extra memory usage. Subsequent changes should bring this overhead down

[sanitizer] allocator: remove kPopulateSize and only use SizeClassMap::MaxCached; ensure that TransferBatch size is a power of two, refactor TransferBatch creation/destruction into separate functions.
