Code quality: use compat functions for Android 13 type extras

[jpelgrom]

Summary

While reviewing the recent camera widget PR I noticed the following nice inline function, which I wanted to add/use in other places where we currently have an if/else for the type in extras:

android/app/src/main/java/io/homeassistant/companion/android/widgets/camera/CameraWidget.kt

Lines 270 to 277 in e525935

	private inline fun <reified T : Serializable> Bundle.getSerializableCompat(key: String): T? {
	return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
	getSerializable(key, T::class.java)
	} else {
	@Suppress("DEPRECATION")
	getSerializable(key) as? T
	}
	}

It turns out Google was one step ahead of us and actually added compat classes that do this, so in this PR all relevant usages (including the camera widget inline function) are replaced with the compat functions, to clean up the code a bit.
