Re: [w3c/webcomponents] Events whose composed flag should be true (#513)

Here is the exhaustive list. This might be a good starting point, hopefully.

I think it is important that we can know the *rationale* how we can make the list.
So here is how to *reproduce* the list.

```
1. Go to https://w3c.github.io/uievents/.
   Get every event types from Chapter 5, excluding events in Chapter 5.1
   -> We got:
      Focus Events:
        blur
        focus
        focusin
        focusout
      Mouse Events:
        click
        dblclick
        mousedown
        mouseenter
        mouseleave
        mousemove
        mouseout
        mouseover
        mouseup
      Wheel Events:
        wheel
      Keyboard Events:
        keydown
        keyup
      Composition Events:
        compositionstart
        compositionupdate
        compositionend
2. Go to https://w3c.github.io/touch-events/
   -> We got:
      Touch Event:
        touchstart
        touchend
        touchmove
        touchcancel
3. Go to https://w3c.github.io/pointerevents/
   -> We got:
      Pointer Events:
        pointerover
        pointerenter
        pointerdown
        pointermove
        pointerup
        pointercancel
        pointerout
        pointerleave
        gotpointercapture
        lostpointercapture
```
