[API View] [Java] Show metadata for Gradle packages

Similar to the Maven metadata in Java API views, we should support showing Gradle metadata like artifact name, group id, version, dependencies etc. All Android libraries use Gradle and there is a consideration to move the Java client libraries to Gradle as well.


Start with the Java API view and its existing Maven metadata support, then compare the requested Gradle metadata fields with the behavior shown in the issue. Done means Gradle package views display the artifact name, group ID, version, dependencies, and other available metadata consistently with Maven views.
