Adding typed Parcel read APIs for Serializable.

Added typed read API of `readSerializable`, that takes
an extra Class<T> parameter to check that the class written
on the wire is the same or a descendant from the one provided
as argument.

Doing so could enhance the security of Parcel deserialization,
as it would prevent unexpected types of objects being deserialized.
