* 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.

Many types used directly in the `libservo` API are in the
`script_traits` crate, which was created to break circular dependencies.
Move all API exposed types to `embedder_traits` which now contains types
exposed via the `libservo` embedding API. Also expose these at the root
of the `libservo` `servo` crate so that the API won't break when they
move around in the future.
The idea with `embedder_traits` in the future is that it contains types
that are available throughout servo because they are used in the
embedding API and thus should have minimal dependencies on other Servo
crates (a bit like `base`).

* Add simple fling implementation
Add a simple fling implementation, which depends on a refresh tick from the
embedder.
Currently this refresh tick is only implemented for OpenHarmony
(using the vsync signal).
The fling implementation is very simple, without any fancy things like acceleration.
This can be improved in the future.

There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.
