Add wait event timeout count to session wait samples

[rluidash]

Description

Adds oracledb.wait.timeouts to the db.server.session.wait_sample event, sourced from V$SESSION_EVENT.TOTAL_TIMEOUTS. This reports, per session and wait event, how many waits ended in a timeout — completing the wait-event picture alongside the existing oracledb.wait.count and oracledb.wait.duration fields.

The value comes from the same V$SESSION_EVENT row the receiver already reads for the wait-sample event, so this adds one column to the existing query and one attribute to the existing event — no new query, metric, or collection path. The field is part of the wait-sample event, which is disabled by default.

Fixes #49934

Testing

Extended the session-wait-event scraper test to assert the new attribute is emitted with the expected value from the fake DB client.
