Reviewed by Alex Christensen.

Modify `WCBackingStore` so its serialization can be generated. Pass an
`ImageBufferBackendHandle` through IPC. Add a constructor to create from
a handle, and a method to retrieve a handle from an instance. Adding
these allows the serialization framework to work on the class.
