LibWeb/EventHandler: Ignore repeated keyup events

Browse Source 
Platforms such as X11 will typically send repeated keyRelease/keyup
events as a result of auto-repeating:

  * KeyPress (initial)
  * KeyRelease (repeat)
  * KeyPress (repeat)
  * KeyRelease (repeat)
  * ad infinitum

Make our EventHandler more spec-compliant by ignoring all repeated keyup
events. This fixes long-pressing the arrow keys on
https://playbiolab.com/.
