Return supported event types when opening a session

[dmondrik]

What does this Pull Request accomplish?

• It includes the supported events for a newly-opened session as part of the "Open" response.
• This copies the latest output from scrapigen. The update is in a pending PR there.

Why should this Pull Request be merged?

The VISA client needs to know which event types are supported for a given session.

What testing has been done?

• Built and walked through it in the debugger.
• I updated the integration tests to account for the new library calls. Added both success and failure cases.

FYI main is locked as the release is finalized on AzDo / we bump the grpc-device version on the AzDo side for new exports. This should be resolved early next week. Alex, Maxx, or I can then unlock main here in grpc-device.

Main is unlocked now.
