tests: refactor event sequencing expectations for simple launch

Browse Source 
Move MetaEvent from the integration test into shared test infrastructure
and expose it for reuse. Add a Guest helper that returns the expected
sequential events for simple launch, and update the integration test to
consume this helper instead of maintaining a local event list.

Adjust expected behavior for confidential VMs by omitting the disk reset
event, which is not guaranteed to be emitted in that mode. Preserve the
existing expected sequence for non-confidential VMs.
