LibGUI+WindowServer: Add new `WMEvent` Super+Digit

This adds a keyboard event for Super+0 to Super+9. Later to be consumed
in the taskbar.

Currently only this keyboard sequence is supported:
  - Super key down
  - Digit key down

But not this:
  - Super key down
  - Digit key down
  - Digit key up
  - Digit key down
