tdf#156033 sw: Don't capture mouse when executing file dlg

When the mouse is captured in
`SwView::InsertGraphicDlg`, temporarily
release it while executing the file dialog,
so the user can use the mouse to interact with
the file dialog.

At least with qt5/qt6/kf5, this would otherwise
not work in the file dialog shown after clicking
on a previously inserted Picture Content Control,
because `QWidget::grabMouse()`'s "other widgets
get no mouse events at all" [1] apparently applies
for the file dialog and other running applications
as well.
