LibWeb: Defer mouse events from TextNode to Label

Browse source 
A label's format is: <label>Label text</label>

So, a TextNode is created as a child of the Label node, and EventHandler
will send events to the TextNode. This changes TextNode to accept mouse
events if its parent is a Label, and to forward those events upward.
