amend cx_Oracle version checks, setup.cfg to oracle 8

Fixed issue where the cx_Oracle dialect claimed to support a lower
cx_Oracle version (7.x) than was actually supported in practice within the
2.0 series of SQLAlchemy. The dialect imports symbols that are only in
cx_Oracle 8 or higher, so runtime dialect checks as well as setup.cfg
requirements have been updated to reflect this compatibility.

Fixes: #10470
