feat(bigquery): add ArrowQueryPageFetcher for Arrow query result pagination

[jinseopkim0]

This PR introduces ArrowQueryPageFetcher to handle pagination for queries executing with QueryResultsFormat.ARROW.

Summary of Changes

• Implements ArrowQueryPageFetcher implementing NextPageFetcher<FieldValueList>.
• Connects to the default storage read stream to fetch subsequent row pages.
• Leverages ArrowDeserializer.loadArrowRows to deserialize Arrow record batches into FieldValueList collections with offset and maxResults bounding.
• Adds ArrowQueryPageFetcherTest covering single-page, multi-page, max-results, and serialization behaviors.

Code Review

This pull request introduces ArrowQueryPageFetcher, a NextPageFetcher implementation designed to paginate query results returned in Arrow format by reading from a gRPC storage read stream. It also adds comprehensive unit tests in ArrowQueryPageFetcherTest.java. The review feedback highlights serialization issues in ArrowQueryPageFetcher: the buffer queue should be marked as transient to prevent duplicate data upon deserialization, and it must be lazily initialized in getNextPage() to avoid a NullPointerException after deserialization.

Code Review

This pull request introduces the ArrowQueryPageFetcher class in BigQueryImpl.java to support paginating query results returned in Arrow format via the gRPC storage read stream. It also adds a comprehensive suite of unit tests in ArrowQueryPageFetcherTest.java to verify its behavior, including pagination, limit handling, error cases, and serialization. There are no review comments, so no feedback is provided.

This pull request introduces the ArrowQueryPageFetcher class in BigQueryImpl.java to handle pagination for query results returned in Arrow format via the gRPC storage read stream. It also updates the read settings configuration to use NoHeaderProvider as a default, and adds a comprehensive suite of unit tests in ArrowQueryPageFetcherTest.java to verify single and multi-page fetching, max results handling, error conditions, and serialization. There are no review comments, and I have no feedback to provide.
