tests: Provide copy test to validate 1xN streams

Validate that a 1xN stream can be read through the RPF and written
through the WPF.

The test framework does not currently support processing images where
the stride does not match the output width - so the testing is currently
limited to testing only the vertical direction in this aspect.
