[Build] Fix configuration cache issues with install task

* `install` task provided by `maven` plugin doesn't support configuration cache so replace `maven` plugin with `maven-publish` and use task that is subtype of PublishToMavenRepository. `maven-publish` partially support configuration cache, see https://github.com/gradle/gradle/issues/13468
* Apply `signing` plugin only if it really needed. The plugin doesn't support configuration cache. See https://github.com/gradle/gradle/issues/13470
