PPTX import: implement native handling of a color's luminance offset

This was already handled in oox/ at import-time: this adds it to the doc
model, including UNO API and PPTX import.

This is a dependency PPTX export and UI, and also the last transform
which is easy to generate from the PowerPoint UI and we didn't import to
the doc model.
