Provide HotkeyState on Global Shortcut Events (#3822)

* Only react to hotkeys that are pressed

The global shortcuts are otherwise also triggering when the hotkey is
being released. This affects at least Windows.

* Provide `HotkeyState` on Global Shortcut Events

Instead of ignoring the events where the shortcut is released, the state
is now provided as an argument to the event handler.
