Add `MutableStateFlowSerializer` for serializing `MutableState`

- Introduced an inline `MutableStateFlowSerializer` function to infer and retrieve the appropriate `KSerializer` for `MutableStateFlow` of a serializable type.
- Added an overload of `MutableStateFlowSerializer` that accepts an explicit `KSerializer` for the wrapped type, allowing for customizing the `KSerializer`.
- Implemented `MutableStateFlowSerializerImpl`, a private class that handles the serialization and deserialization logic for `MutableStateFlow`, delegating inner value processing to the provided `KSerializer`.
- Only `KSerializer<MutableStateFlow<T>>` is exposed; the `MutableStateFlowSerializerImpl` remains private.

RelNote: "Add `MutableStateFlowSerializer` for serializing `kotlinx.coroutines.flow.MutableStateFlow`."
