tdf#127958 crash adding 2 or more files into writer master document

just make SfxMedium use shared_ptr, rather than the sometimes yes,
sometimes no, ownership.

used the SfxItemSet copy ctor to make a copy of the itemset, but the orig
itemset was a SfxAllItemSet not a SfxItemSet.

an SfxAllItemSet allows all items to be added but a plain SfxItemSet only
allows items in certain ranges to be inserted. Upshot is that later on the
filename property cannot be set in the itemset, so file can't be opened.

tdf#128898 import text from file with text-decode failed

these are std::shared_ptr so we can return to passing in the original
SfxAllItemSet again to fix the problem
