Allow configuring keyboard shortcuts (#9643)

Closes #2689

The design of the respective code is loosely based on KDE's KActionCollection. The ActionCollection manages all actions that can be shortcut configured. These actions are then exposed in the config and a user can assign a different shortcut.

Actions inside the MainWindow have been added to the ActionCollection.
