[sanitizer] change SizeClassAllocator64 to accept just one template parameter instead of 5. First, this will make the mangled names shorter. Second, this will make adding more parameters simpler.

[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

Revert "[sanitizer] Allow the sanitizer allocator to use a non-fixed address range. An allocator with a non-fixed address range will be attack-resistan. NFC for the sanitizers at this point."
...
This reverts commit r267094, because it broke a lot of MSAN tests in AArch64.
Being NFC and all, this needs some deeper investigation before it goes in again.
