[KSP2] kotlin-inject doesn't link typealiases for functions to their function

[ZacSweers]

Repro from here: https://github.com/slackhq/circuit/blob/main/samples/kotlin-inject/src/main/kotlin/com/slack/circuit/sample/kotlininject/main.kt#L22

typealias KotlinInjectApp = @Composable () -> Unit

fun main() = application {
  val app = remember { AppComponent::class.create().kotlinInjectApp }

  Window(onCloseRequest = ::exitApplication, title = "Sample") { app() }
}

@Inject
@Composable
fun KotlinInjectApp(circuit: Circuit) {
  CircuitCompositionLocals(circuit) { CircuitContent(MyScreen("Circuit")) }
}

To test:

• Checkout the repo
  • If this PR hasn't merged yet, checkout that branch
• Set KSP2 to true in /samples/kotlin-inject/build.gradle.kts
• Run ./gradlew :samples:kotlin-inject:kspKotlin

This works fine in KSP1, let me know if this is a KSP bug I should file upstream. This is on KSP 2.1.0-1.0.29.

@ZacSweers are you able to test your repro against #350?

I can give it another try once it's in snapshots 👍
