Tests opencasacde/*: Add three output variants

All tests produce a visually correct output. The test fails due to

 - a different mesh generator used in opencascade 7.4.0 placing vertices
   slightly differently

 - a slightly different refinement behavior when linking against libc++
   versus libstdc++

For now, just be pragmatic and add an output variant for each. We might
have to find a smarter solution in the future

In reference to #10073
Closes #10086
