Stop using VersionedObject in resource.Builder, use unstructured

Remove the need for kubectl callers to distinguish between unstructured and versioned / type aware builders.  The factory should create a single builder than can be set to return unstructured objects.  Callers can then use one of the new helpers on `resource.Info` to convert the objects into the desired form - `Internal()` for printers, `Typed()` for external versions, and `Unstructured()` to ensure the object is in the right state.  Leverages the new scheme support for unstructured conversion so that higher level callers can perform best effort conversion (get typed versions if you have them, otherwise use default behavior).  

`get.go` demonstrates this by removing the previous logic that depended on the underlying scheme.  Other commands are updated to be consistent.

Includes #55650 and #55647.
