Kenneth Myhra 53394230ca LibWeb: Reorganize definitions and includes to avoid circular references
This is necessary to avoid a circular reference when including
Serializable.h in DOMException.h.

This moves the definition of SerializationRecord, SerializationMemory,
and DeserializationMemory into LibWeb/Forward.h so that Serializable.h
only needs to include LibWeb/Forward.h.
