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
