Add more CSV information to the PackageManifest

Transfer `spec.relatedImages`, `spec.minKubeVersion`, and `spec.nativeAPIs`
information from the CSV onto the packagemanifest response.

CSVs are transformed from the in-bundle representation to the packagemanifest
by selecting fields to display. Those additional fields will support the UI.
