SerializedLambda class

To represent serialized lambdas, we need a class to capture its serialized form, tentatively called SerializedLambda. It needs to capture the following nominal information about a lambda:

    private final String capturingClass;
    private final String functionalInterfaceClass;
    private final String functionalInterfaceMethodName;
    private final String functionalInterfaceMethodSignature;
    private final int functionalInterfaceMethodKind;
    private final String implClass;
    private final String implMethodName;
    private final String implMethodSignature;
    private final int implMethodKind;
    private final String instantiatedMethodType;
    private final Object[] capturedArgs;

This class will have a readResolve() method which reflectively (in a doPrivileged block) finds the $deserialize$ method on the capturing class, and passes itself to that method to perform the actual deserialiation.
