embeddedobj: add a status indicator for the Further objects dialog

Inserting a large file can take a while, and we do it on the main
thread, so the UI is frozen during the operation.

Create the progressbar in cui, which is allowed to link against sfx2/
and then pass it down to embeddedobj/. Similarly for the label of the
progressbar, again because cui is allowed to link against svx/.
