tdf#120028 PPTX import: map shapes with multiple columns to table shapes

This is a combination of 3 commits.

1st commit:

Longer term the core Impress shape has to be improved so that it can have
text in multiple columns.

Shorter term, map text with multiple columns to table shapes, that gives
correct layout in many cases and requires changes to the import filter
only.

(cherry picked from commit aef569ed83a3ccc02639e5b2a1c7cc131ba262fc)

Commit #2:

Related: tdf#120028 PPTX import: fix font size of multi-col shape text

Normal shapes have a TextFitToSize property for this, but table cell
content has to be scaled manually, as the rendering has no automatic
support for them. Luckily the file format has the info we need to scale
at import time.

(cherry picked from commit c8b2849d140677f7b35523096eb2bc715b3dc507)

Commit #3:

Related: tdf#120028 PPTX import: fix font color of multi-col shape text

Not just font color, anything defined via list styles were not imported.

(cherry picked from commit 800bf1071a30955ff70373b2fb5886eadce59dee)
