tdf#143574 OOXML export/import of textboxes in group shapes

In this part, oox module has been modified in order to prepare
for WPG handling during OOXML import. Note: Wpg is the drawingML
equivalent of v:group, supporting text boxes in the group.

1) Added new parameter for WpgContext to support nested
Wpg shapes, and WPS enabled for the WPG member shapes.

2) A bug has fixed, where group member line shape and
connector shapes have wrong positions before in the group.

3) Unit tests had to be modified, and 3 of them disabled
temporarily due to missing Writerfilter implementation (what
will be the next commit)

Now group shapes can have textboxes and the text is imported
for that, but complex content is still missing (this will be
fixed in writerfilter by the next commit).

Known issue: WPG shapes with textboxes in floating table
have issues during import at floating table conversion, so until
this is not fixed this function is disabled for shapes in tables
(will be fixed a follow-up commit later).

Follow-up to commit 19394a924fdc486202ca27e318385287eb0df26f
"tdf#143574 sw: textboxes in group shapes -- part 4".
