This gives internal its own res directory, and pushes the build files down into the source directory (as it is with all our other non-widget packages). Ideally new things don't really get added to this package (instead they can be added to feature/component-specific packages as package private). A few new packages had to be created in order to break circular dependencies between widget and internal. This commit also fixes a number of problems with the Gradle build, as they were mostly related to dependency issues or things not being included in settings.gradle. The next step here is to do the same for the widget package, and turn the lib build files into something that just exports the other library packages. PiperOrigin-RevId: 179866428
