wic: direct: move UUID generation to PartitionedImage
Moved code that generates partition UUIDs from DirectPlugin to PartitionedImage class as it's more logical to have it there. This allows the code to be reused by other imager plugins. Got rid of having yet another list of partitions in PartitionedImage. Reused the list passed from DirectPlugin.
