* implement Touchevent prevent default behavior
* The status change logic of the `TouchHandler` is changed.
> The `WaitingForScript` state is canceled. TouchAction can be identified
based on the current touch type and numbers if touch points.
* Sends current event to script thread along with recognized `TouchAction`.
> After dispatch event, script thread sends a `TouchEventProcess(EventResult)`
message to main thread. If the event is set to `DefaultAllowed`, the
corresponding `TouchAction` information is added.
* After receiving `DefaultAllowed(TouchAction)` message, main thread executes corresponding action.
> `DefaultPrevented(TouchEventType)` is received. Use `prevent_click` to mark
that the default `Click` is blocked, and `prevent_move` to mark that the
default `Scroll` and `Zoom` are blocked. In this way, all TouchActions
implement preventDefault.

This change exposes a single `InputEvent` type and now there is only a
single delegate method for this `WebViewDelegate::notify_input_event`.
- Clipboard events are now handled as `EditingAction` inpute events. In
the future this can include things like "Select All", etc.
In addition, many parts of the dance to pass these events can now be
simplified due to this abstraction.
- All forwarded events are handled the same way in the `Constellation`,
though they may carry an optional hit test (for events that have a
`point`) which affects which `Pipeline` they are sent to.
- In the `ScriptThread` we now accept these `InputEvents` and use them
everywhere. Now all "compositor events" are "input events".
- This allows removing several data structures which are no longer
necessary.
- We no longer inform the embedder when an event was handled by a
WebView as that was only important for a MDI feature that will
no longer be so important the full-featured `WebView` API.
