Set `metalavaK2UastEnabled` to `false` in `savedstate` 
 
* The `updateApi` task was incorrectly failing due to `ReadWriteProperty` being in the public API. As a temporary solution, we are disabling `metalavaK2UastEnabled` as per the recommendation of the tooling team.

Add `saved` Serialization delegates to `SavedStateRegistryOwner 
 
* The new `saved` property delegate enables the use of KotlinX Serialization with any SavedStateRegistryOwner (`Activity`, `Fragment`, or `NavBackStackEntry`). 
* The new `saved` property delegate behaves lazily. 
* Note that an inaccessible property will not participate in the saving and restoring process, as its default value would be evaluated. Therefore, there is no reason to perform restoration in such cases. 
 
RelNote: "Add `saved` property delegate to `SavedStateRegistryOwner`, allowing `@kotlinx.serialization.Serializable` annotated classes to be saved during process death."

Fix `SavedState.contentDeepEquals` with nested `SavedState` on non-Android platforms 
 
* Non-Android platforms introduce a new `SavedState` symbol that wraps a `map`. Therefore, it has no default implementation for handling content deep equality like a conventional `map`. 
* Note: The original implementation for non-Android used interface delegation to implement the `Map` interface, but we have changed that to avoid exposing the `Map` API and consistently require clients to use `read`/`write` on all platforms for accessing the content. That design change caused this bug. 
* Includes support for primitive arrays.

Fix `SavedStateReadWriteProperty` saving outdated values 
 
* `value` was incorrectly resolving to the initial value instead of the updated `this.value`. 
* Includes a fix in the unit test to catch this problem if it ever happens again.

Fix empty SavedStates not getting restored 
 
Fixes an issue that when we restore an empty SavedState (e.g. from an empty List or an object without properties) we will ignore it and call the initailizer instead.
