The inline docs for `folly::Bits` already mention that storage is expected to be little-endian. This change enforces little-endianness by using `folly::Endian` for load/store operations. This should be a no-op on little-endian systems. The main motivation for this change is that it immediately enables fbthrift Frozen2 files to be exchanged between little- and big-endian systems.
