sstables: mc: sign-extend delta local_deletion_time and delta ttl
...
Follow Cassandra's encoding so that values that are less than the
baseline encoding_stats will wrap-around in 64-bits rather tham 32.

Collect encoding statistics for memtable updates.
...
We keep track of all updates and store the minimal values of timestamps,
TTLs and local deletion times across all the inserted data.
These values are written as a part of serialization_header for
Statistics.db and used for delta-encoding values when writing Data.db
file in SSTables 3.0 (mc) format.
For #1969 .
