The FWU specification now has two versions of the FWU metadata structure, and both are to be supported. Introduce a version agnostic structure for storing information about the FWU updatable images. This allows for a split of common version agnostic FWU code and version specific code.
The version specific code is then responsible for arranging the data as per the corresponding metadata structure before it gets written to the metadata partitions.
