cool#8270 sw lok: fix bad statusbar pagenum string on async binding update

This is similar to commit 51d8a2ef54751403fa707816e27ddb4e7faa8231
(cool#7492 sfx2 lok: fix bad view id / statusbar string on async binding
update, 2024-01-08), but here the problem was that the async job tried
to get the current view from the model, which is not correct.

Fix the buggy page number string in the status bar by requesting callers
of SwViewShell::GetFirstLastVisPageNumbers() to provide the view, given
that SwViewShell itself doesn't have access to SwView, only the
SwWrtShell subclass would have that.

(cherry picked from commit ce350b840ce806c4060f9fdbd67fa4c95c82edf5)
