Add/update tests for copying ALPHA_8 to HARDWARE

With Ibfec753b1f82b0ff97341a742b2933e2f18b234a, this is now supported on
some devices. Update existing tests to allow the copy to succeed; now
those same tests will verify the native format matches.

Add a new test verifying that ALPHA_8 + HARDWARE does not have a
ColorSpace.
