tdf#136267 OOXML Chart Import: create main category axis labels once

because InternalDataProvider can not handle different category names
on the primary and secondary category axis.

Revert e0b0502516a10181bbd1737b93b38b2bba4c98e8 commit, except
the relevant unit test.

Regression from commit: e0b0502516a10181bbd1737b93b38b2bba4c98e8
(tdf#128016 Chart OOXML Import: fix duplicated category labels)

Also fix tdf#129994 (FILEOPEN - hang at import time), which is a
a regression from commit fa0a981af41a2606541eec1cb20a379a739691e0
(tdf#114166 DOCX chart import: fix missing complex categories)
