the vmo handle values in the returned struct are the same as those managed by source, so the

caller must ensure that the source out-lasts the returned struct (or at least, outlasts any usage

of the vmo handles in the returned struct)

When we provide move, we only provide move from llcpp, not from FIDL C.

See fidl_struct.h's TakeAsLlcpp() for a way to convert from FIDL C to llcpp first.
