Jacob Boerema aed3d9c779 plug-ins: fix #6258 Hierarchical XMP tag should be written to Array
When saving XMP metadata were using gexiv2_metadata_get_tag_string for all
tags, even those that can have multiple values. This caused those values
to be saved as one value instead of multiple.

To fix this we use gexiv2_metadata_get_tag_multiple, except for XmpText.
Then we add all returned values for that tag separately to our metadata.
