WebContent: Allow the WebContent process to trigger repaints

Browse source 
After layout, we may want to repaint the page, so we now listen for the
PageClient::page_did_invalidate() notification and use it to drive a
client-side repaint.

Note that an invalidation request from LibWeb makes a full roundtrip
to the WebContent client and back since the client drives painting.
