For now, the only extension function on the `Player` has been used in a Compose demo. It can be promoted to a proper module where in the future other extension functions will reside. Given that `Player` is in `androidx.media3.common`, the corresponding KTX library for it is `androidx.media3.common-ktx`
To start using the new `suspend fun listen`, one must add `androidx.media3:media3-common-ktx` as a Gradle dependency and `import androidx.media3.common.listen`

Given that `Player` interface is written in Java and is has a callback-based Listener interface, we need an adapter for the Kotlin-native world.
This change introduces a suspending function `listen` that creates a coroutine, in order to capture `Player.Events`.

Underneath, it delegates to either
* `AndroidExternalSurface` (equivalent of SurfaceView), which is generally better for power and latency
* `AndroidEmbeddedExternalSurface` (equivalent of TextureView) which is better for interactions with other widgets or applying visual effects through the graphicsLayer
Note: the resulting surface is stretched across the whole screen. Aspect ratio handling will be addressed in the follow-up changes.
