oox: extract adjustment names by type from spec XML

The naming of adjustments is not consistent for drawingML shapes, some
of them have the first parameter as "adj1", some of them have it as
"adj". We already have a script that generates some code based on these
XML files, make it generate a function that returns the naming for each
type.

fdo#73215 oox: don't assume single adjustment is adj during export

So far adjustment names were either taken from the document model, or in
case there the name was empty, either "adj" was used (in case of a
single adjustment) or "adj1", "adj2", etc.

The problem is that there is no consistency here, e.g. this behavior was
correct for "cube" (single adjustment is called "adj"), but not for
"bentConnector3", where the single argument is called "adj1".

Instead of trying to guess or build a long list manually, use the new
ooxDrawingMLGetAdjNames() to write the correct names.
