build(Gradle): fix Kotlin compilation errors in instrumentation tests

The "Unresolved reference" errors are for hidden symbols from the
prebuilt AOSP's android.jar library, that is not visible anymore in the
instrumentation tests when loaded via compileOnly API.

Since Kotlin 1.8, it's required to explicitly use androidTestCompileOnly
API to load a library for the instrumentation tests. See for more
https://kotlinlang.org/docs/whatsnew18.html#kotlin-multiplatform-a-new-android-source-set-layout
