slk e12753eb71 Track each SST's timestamp information as user properties (#9093) 
Summary:
Track each SST's timestamp information as user properties https://github.com/facebook/rocksdb/issues/8959

Rockdb has supported user-defined timestamp feature. Application can specify a timestamp
when writing each k-v pair. When data flush from memory to disk file called SST files.
Each SST files consist of multiple data blocks and several metadata blocks. Among the metadata
blocks, there is one called Properties block that tracks some pre-defined properties of this SST file.

This PR is for collecting the properties of min and max timestamps of all keys in the file. With those
properties the SST file is more convenient to tell whether the keys in the SST have timestamps or not.

The changes involved are as follows:

1) Add a class TimestampTablePropertiesCollector to collect min/max timestamp when add keys to table,
   The way TimestampTablePropertiesCollector use to compare timestamp of key should defined by
   user by implementing the Comparator::CompareTimestamp function in the user defined comparator.
2) Add corresponding unit tests.
