fix: Google Ads dependency conflicts

[bitsandfoxes]

Google Ads comes with its own External Dependency Manager that copies the aar into the project's plugin folder. This leads to issues during runtime.
Since we don't use the Android AppLifecycle (session auto tracking) feature we disable adding breadcrumbs by default.
