[6.0.x] Fixed #36646 -- Added compatibility for oracledb 3.4.0.

The Database.Binary, Date, and Timestamp attributes were changed from
aliases to bytes, datetime.date, and datetime.datetime to factory
functions in oracle/python-oracledb@869a887819
which made their usage inadequate for isinstance checks.

Thanks John Wagenleitner for the report and Natalia for the triage.
