Description

As stated above we need to replace the BoundedSource with OffsetBasedSource in BigQuery connector (for Java). This will allow both the Java and upcoming Python BigQuery ReadAPI connector to have similar interfaces.

Imported from Jira [BEAM-12013](https://issues.apache.org/jira/browse/BEAM-12013). Original Jira may contain additional context.
Reported by: vachan.

Research direction

Locate the Java BigQuery connector and search for BoundedSource and OffsetBasedSource usages, then inspect how the connector currently exposes its read interface. Done means BoundedSource is replaced in that connector and the Java interface follows the similar shape intended for the upcoming Python BigQuery ReadAPI connector.
