PPTX export: handle theme colors from the doc model for shape text

As a start, do this only in case there are no effects used. If there is
no theme color or there are effects, fall back to the old code.

Also move parseExportStream() from SdModelTestBaseXML up to MacrosTest,
so oox/ test code can use it as well.

(cherry picked from commit f36767fde87191258ea21f3faac0be6ad79328e0)
