Some of errors that can happen during runtime (e.g. OOM) is not an exception, but instead an Error. If that happens, results would be truncated rather than return an error to the user due to finally block handling.

Replacing Exception with Throwable for handling of errors that can happen in the background threads

Code Review

This pull request updates exception handling across several classes, including BigQueryArrowBatchWrapper, BigQueryBaseResultSet, BigQueryFieldValueListWrapper, and BigQueryStatement, to catch and propagate Throwable instead of Exception, preventing silent stream truncation on background threads during critical failures. It also adds unit tests to verify that OutOfMemoryError is correctly propagated. The review comments provide valuable feedback, pointing out that catching Throwable without rethrowing JVM Errors (like OutOfMemoryError) is an anti-pattern that can leave the JVM in an unstable state, and suggest rethrowing these errors after they are enqueued.
