tdf#127696 PPTX export: fix lost outline character formatting

Now outline font property export is supported partially in PPTX
export and in text shape export in other OOXML formats.

Note: OOXML/MSO has customizable Text Fill and Text Outline in
Format Text Effects, while LO has only simple and buggy outline
character formatting property, showing only white or completely
transparent outline fill color. Transparency issues and the buggy
outline font handling of LO (e.g. 1% font color (line) transparency
results 100% fill transparency of the outline text) haven't been
handled yet.
