IMPALA-13252: Consistently use PrintId to print TUniqueId

Some logging formats TUniqueId inconsistently by relying on the Thrift
to_string/toString generated printers. This makes it difficult to track
a specific query through logs.

Adds operator<<(ostream, TUniqueId) to simplify logging TUniqueId
correctly, uses PrintId instead of toString in Java, and adds a verifier
to test_banned_log_messages to ensure TUniqueId is not printed in logs.

> Filter update received for non-executing query with id: 
> TUniqueId(hi=-8482965541048796556, lo=3501357296473079808)

> print query id as the raw Thrift type rather than our colon-delimited format, 
> e.g. "8a4673c8fbe83a74:309751e900000000". This makes it difficult to trace

> Normalize on the colon-delimited format.
