[REVIEW 3-5, 3-6, 3-6-1?] fdo#47434 pptx arrow import

[Korrawit Pruegsanusak]

Hello all,

I'd like to propose [1] which fix fdo#47434 to be included in -3-5,
3-6, and 3-6-1 if possible.

For the detailed explanation, please see in bugzilla starting from comment #13.

Also, the unit test waiting in gerrit [2] couldn't be backported
because I use XShapeDumper available only in master, and my skill
isn't enough to use UNO API. ;)

Thanks!

Best Regards,
