[java-bigquery] Support TableDefinition maxStaleness for CDC

**Describe the solution you'd like**
TableDefinition should support maxStaleness for change data capture (CDC).

**Additional context**
See https://cloud.google.com/bigquery/docs/reference/rest/v2/tables#resource:-table maxStaleness & the [CDC blog post](https://cloud.google.com/blog/products/data-analytics/bigquery-gains-change-data-capture-functionality)

Start with the Java BigQuery TableDefinition entry point and compare its supported fields with the BigQuery tables REST resource documentation, especially maxStaleness. Use the linked CDC documentation to understand the intended behavior; done means TableDefinition supports this CDC setting consistently with the API.
