[Feature] Include platform disabling logic in vertical integrity tests

### Is there an existing feature request for this?

- [x] I have searched the existing issues

### Describe the Feature

Currently, all of our vertical integrity data validation tests (except the geo reports) expect all possible platforms to be enabled and will therefore fail if any are disabled.

Let's include logic to dynamically handle these cases in case we want to run tests on a subset of available platforms.

### How would you implement this feature?

Use the exact same [include_list](https://github.com/fivetran/dbt_ad_reporting/blob/main/models/intermediate/int_ad_reporting__keyword_report.sql) and [enabled_package](https://github.com/fivetran/dbt_ad_reporting/blob/main/models/intermediate/int_ad_reporting__campaign_report.sql) logic and if-conditionals we use in the respective intermediate models.

### Describe alternatives you've considered

Leave it as is and only test with all platforms enabled.
