Subject: ci: Optimize Gradle build performance in Github Actions

This change updates the Github Actions Gradle workflows in order to
improve the runtime performance of these workflows. We have now enabled
build caching as well as parallel builds to speed up the build process.
Moreover, we now cache the Gradle wrapper.
