use maven-publish plugin (#31611)

Summary:
Gradle has been showing below warning for a while, and this PR fixes the warning using maven-publish plugin, thus taking us one step closer to Gradle 7.x.

> The maven plugin has been deprecated. This is scheduled to be removed in Gradle 7.0. Please use the maven-publish plugin instead. Consult the upgrading guide for further information: https://docs.gradle.org/6.9/userguide/upgrading_version_5.html#legacy_publication_system_is_deprecated_and_replaced_with_the_publish_plugins

Configured maven-publish plugin according to https://developer.android.com/studio/build/maven-publish-plugin, also added **installArchives** task for backwards compatibility.
