replace deprecated KActionMenu::setDelayed
This starts a set of MRs to update recent deprecations in the frameworks land.
Compiled without errors on Fedora, Ubuntu and Opensuse.
TEST PLAN:
the only usage is in Bookman button, the popup should be drawn immediately when clicking on both buttons or using the CTRL+D shortcut (the menu should the drawn immediately below the button) - the right panel Bookman still has a mysterious ALT+B shortcut...
Also, I sorted the macros by the version of when they will be removed, KDE first, then Qt.
