Add ability to encode/decode Java and Android types supported by Bundle 
 
Here's a list of types added: 
 
Classes/type aliases: 
 
* SavedState 
* android.util.Size 
* android.util.SizeF 
 
Interfaces: 
 
* CharSequence 
* java.io.Serializable 
* android.os.Parcelable 
* android.os.IBinder 
 
Collections: 
 
* Array<out CharSequence> 
* Array<out android.os.Parcelable> 
* ArrayList<out CharSequence> 
* ArrayList<out android.os.Parcelable> 
* android.util.SparseArray<out android.os.Parcelable> 
 
`SavedState` is supported on all platforms while the other types are supported on Android only.

Open built-in serializers for Interface types 
 
Make `CharSequenceSerializer`, `JavaSerializableSerializer`, and `ParcelableSerializer` open generic classes instead of singleton objects so that users can inherit and define serializers for their own subtypes. This can be used to prevent `SERIALIZER_TYPE_INCOMPATIBLE` lint warning. For example, instead of suppressing the warning like this: 
 
``` 
@Serializable 
data class CharSequenceContainer( 
    @Suppress("SERIALIZER_TYPE_INCOMPATIBLE") 
    @Serializable(with = CharSequenceSerializer::class) 
    val value: String 
) 
``` 
 
Users can do: 
 
``` 
class StringAsCharSequenceSerializer : CharSequenceSerializer<String>() 
 
@Serializable 
data class CharSequenceContainer( 
    @Serializable(with = StringAsCharSequenceSerializer::class) 
    val value: String 
) 
``` 
 
The serializers can also be used directly with subclasses. For example, users can now write: 
 
``` 
encodeToSavedState(serializer = CharSequenceSerializer(), value = "foo") 
``` 
 
Since CharSequenceSerializer is now generic, it works with value `foo` even though it has a static type of String. 
 
We also made some changes to all the built-in serializers: 
 
- Changeed all built-in serializers from singleton objects to classes so that they're consistent with `CharSequenceSerializer`, `JavaSerializableSerializer`, and `ParcelableSerializer`. 
 
- Moved the actual `getXXX()`/`putXXX()` from `platformSpecificEncodeSerializableValue`/`platformSpecificDecodeSerializableValue` to `serialize()`/`deserialize()` functions of these serializers. This way we don't require special logic in `SavedStateEncoder.encodeSerializableValue()`/`SavedStateDecoder.decodeSerializableValue()`.
