KAFKA-10369: Add TimestampAndOffset value type of deduplication store (1/N)

[AyoubOm]

Summary

This is a first PR for adding deduplication operator to Streams DSL. See this global PR draft for reference #22189

This PR adds the TimestampAndOffset class which will be used as a the value type of the deduplication store. The store keeps track of the records seen so far, and will be used by the processor to deduplicate records. See wiki and mail thread discussion for the reason we need the timestamp and offset.

In brief:

• Deduplication is bounded in time and the store doesn't keep records forever - old records should be evicted from the store => Hence Timestamp

• Records may be processed twice in case of a failure - we need to track records that have been saved in the store and still not committed => Hence Offset
