Add functions to encode serializable objects to and decode serializable objects from `SavedState`. 
 
We do this by implementing an `Encoder` and a `Decoder` that writes and reads a `SavedState` output format for Kotlin Serialization (https://github.com/Kotlin/kotlinx.serialization). The format represents a Kotlin Serialization "primitive" as their corresponding `SavedState` supported type, and represents a "composite" in a `SavedState` with its property names as keys. Nested composites are represented by nested `SavedState`s. 
 
Here are some other design choices we made: 
 
1. We don't record size for collections and rely on the size of the `SavedState` in decoding so that collections and non-collections are treated the same. 
2. To save space, we don't encode default values by default (it can be tweaked with `@EncodeDefault` with plugin-generated serializers). 
3. To support nullable parameters with default arguments (e.g. `val a: String? = "foo"`) and for `SavedState` size to be correct for collections, we encode `null`s. 
4. To keep things simple we don't support specifying custom `SerializersModule`s for now. 
 
Please note that when using Kotlin Serialization and these functions as a `Parcelable` alternative on Android there's a performance overhead because of the extra serialization needed. 
 
Also note that on Android we don't have built-in support for Android or Java specific types supported by `Bundle` or `Parcel` yet (e.g. `Exception`, `java.io.Serializable`, or `IBinder`).  We may consider adding these types in the future. 
 
Relnote: Add encodeToSavedState() and decodeFromSavedState() functions

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Fix `SavedStateReadWriteProperty` saving outdated values 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.
