LibWeb+WebContent: Modify did_request_scroll() IPC to take x&y deltas

Browse source 
This is in preparation for implementing JS scrolling functions, which
specify both x and y scrolling deltas. The visible behavior has not
changed.

Also, moved the "mouse wheel delta * 20" calculation to the
`EventHandler` since the JS calls will want to work directly in pixels.
