Fix host-to-device copy missing sync in strings/duration convert (#17149

)

Fixes a missing stream sync when copying a temporary host vector to device. The host vector could be destroyed before the copy is completed. Updates the code to use vector factory function `make_device_uvector_sync()` instead of `cudaMemcpyAsync`
