41e633826a bcachefs: add bcachefs xxhash support
xxhash is a much faster algorithm compared to crc32.
could be used to speed up checksum calculation.
xxhash 64-bit only, as it is much faster on 64-bit CPUs compared to xxh32.

data as incompressible, rebalance will keep rewriting incompressible
data over and over.
