Start to enable built-in kotlin. Let's check this works before doing this automatically for all builds via the migrator. This only affects example apps.

Enabling last outstanding example plugin app interactive_media_ads in a follow up PR: #12912. It requires updating a kotlin testing dependency (in the plugin module; not the example app) that breaks when built-in kotlin is enabled.

Partially Addresses flutter/flutter#189235

Enables `android.builtInKotlin=true` for the `interactive_media_ads` plugin example app.

Split out of #12883, which flips the same flag for every other Android example app. This package was held back because it is the only one that needs an accompanying dependency change.
