The lightweight inheritance mechanism used for GtkShortcutTrigger is not
going to be usable by bindings, because boxed types cannot have derived
types.
We could use GTypeInstance and derive everything from that, like
GParamSpec, but in the end shortcuts are not really a performance
critical paths, unlike CSS values or render nodes.
When creating shortcuts, there almost always are a trigger and an action
available for use. So make gtk_shortcut_new() take those as arguments.
Also add gtk_shortcut_new_with_arguments() so people can easily pass
those in, too.
Similar to GtkShortcutTrigger, GtkShortCutAction provides all the
different ways to activate a shortcut.
So far, these different ways are supported:
- do nothing
- Call a user-provided callback
- Call gtk_widget_activate()
- Call gtk_widget_mnemonic_activate()
- Emit an action signal
- Activate an action from the widget's action muxer
Mnemonics need to be triggered with help from the controllers (who
determine the modifiers). Support for that has been added, too.
Mnemonics do not use this yet though.
