kv/kvserver: use proper formatting when debug printing intents

This commit changes the formatting used when printing intents via the
CLI debug command from the default generated Protobuf formatter to our
custom `MVCCMetadata` formatter implementation.  Additionally, the
`MergeTimestamp` and `TxnDidNotUpdateMetadata` fields have been added to
the output.  This changes the debug formatting from the former
example:
