[Java][Flight] Implement JPMS (module-info.java) for Flight module

Blocker: Current grpc-api and grpc-context are not modularized and cannot be used as a module because both of them has the same package named io.grpc

**Reporter**: [David Dali Susanibar Arce](https://issues.apache.org/jira/browse/ARROW-18021) / @davisusanibar

_{**Note**: *This issue was originally created as [ARROW-18021](https://issues.apache.org/jira/browse/ARROW-18021). Please see the [migration documentation](https://github.com/apache/arrow/issues/14542) for further details.*}

Start by locating the Java Flight module and its module-info.java entry point, then inspect how it depends on grpc-api and grpc-context. Check the migration documentation linked in the issue for context on the original ARROW-18021 request. Done means the Flight module can be compiled and consumed as a JPMS module without the conflicting grpc package issue.
