Fix copy-to-clipboard shortcut on macOS

It turns out that the previous implementation, based on installing an event filter in every QAction instance, does not work on macOS, likely due to a Qt bug.

Attempt to work around this by using a different implementation of the same idea, by reacting to ShortcutOverride events in the MainWindow object.

Fixes #10929.
