We want to avoid excess overhead or synchronization in the serialization code paths for Kokkos::View objects whose contents may reside in host-inaccessible device memory. Skip initializing the space allocated for any mirrors, since it's guaranteed to be overwritten, and pass execution space arguments to all allocations and copies to ensure that synchronization only occurs minimally and where we ask for it.
