Add stream and memory-resource parameters to struct-scalar copy ctor #8901

Merged

Investigating issue #8883 I found the cudf::struct_scalar copy constructor does not take a stream or memory resource parameter like the other scalar copy constructors. This PR adds the appropriate signature and implementation.

Also found usage of thrust::device_pointer_cast being used in strings concatenate specialization to get values from an offsets column. This PR changed those to use cudf::detail::get_value instead to honor the current stream.

Nice simplification of the offsets calc, and +1 for removing includes from the tests.
