TIMESTAMP_WITHOUT_TIME_ZONE and TIMESTAMP_WITH_LOCAL_TIME_ZONE fields were
serialized using a hardcoded "yyyy-MM-dd HH:mm:ss" formatter, silently
dropping sub-second precision regardless of the declared column precision.
Add datetimeFormatter(int precision), mirroring the existing timeFormatter,
which appends fractional seconds only when precision > 0. The formatter
instances are cached per precision to avoid repeated allocation.
For StarRocks < 3.1, the fractional part is truncated by the server on
ingestion — no behavioral regression. For StarRocks >= 3.1 (which supports
microsecond DATETIME storage), full precision is now preserved end-to-end.
