Preliminary tasks: Update .gitlab-ci.yml to build automatically for iOS and Android App bundles instead of APK

created three separate stages 1- test_analyze to run the unit tests and print any analyze issues found 2- build_debug to build the app and generate an apk for debugging 3- build_android to build the app and generate an app bundle (.aab) for publishing in google play 4- build_ios to build the app and generate an app bundle (.ipa) for publishing in app store
