Timeout during query compilation or query evaluation should produce notification

[henrymercer]

Describe the bug
If a query compilation or a query evaluation times out, the extension should produce a notification to inform the user of the timeout.

To Reproduce

1. Set codeQL.runningQueries.timeout to 1 second
2. Run a long-running query e.g. a path problem query
3. Observe that the query run notification disappears, indicating that the query run has terminated, however there is no notification informing the user of the timeout.

Expected behavior
When the query run notification disappears, an error notification should be displayed indicating that the query run has timed out.
