refactor: Remove/deprecate/rename old options

This is extracted from #1681

We're doing some different things here:
- `save_marketing_params` over `store_google` because we do much more than just handling Google params with this settings
- Deprecate `verbose` in favor of `debug`
- Retire `inapp_protocol` and `inapp_link_new_window`, we're not using them anywhere, but we'll keep in the type for backwards-compatibility
- Completely remove `__preview_send_client_session_params`, I've checked and it's not being used by anyone in production
