`com.android.test` projects recommend removing dependencies that provide instrumentation tests

**Plugin version**
2.17.0

**Gradle version**
8.12.1

**JDK version**
17

**(Optional) Kotlin and Kotlin Gradle Plugin (KGP) version**
2.0.21

**(Optional) Android Gradle Plugin (AGP) version**
8.9.1

**Describe the bug**
Running `fixDependencies` on an empty com.android.test project that has only android library dependencies to provide ui tests will end up removing the dependencies.

**To Reproduce**
Basic project structure to repro this:
```
:app (com.android.app)
:test-app (com.android.test)
targetProjectPath ':app'
depends on :test-suite
:test-suite (com.android.library)

```

**Expected behavior**
If a `com.android.test` project includes a dependency on an android library that has classes in an `androidTest` configuration, it should not be marked unused.

Start by reproducing `fixDependencies` with the described `:app`, `:test-app`, and `:test-suite` project structure and the `androidTest` sources in the library. Trace how dependencies of `com.android.test` projects are classified, then verify that the dependency providing instrumentation tests is retained rather than reported as unused.
