sw: add DOCX import for semi-transparent text

This is one of the text effects properties, which is already
grab-bagged. That is done in a generic way, so the easiest is to just
read the value from the grab-bag, rather than from the dmapper tokens
directly.

(cherry picked from commit 3a749d7278bbe65cfc063e64460df8af6bc2af47)
