Makoto Kato 28844e8f80 Bug 1639087 - Add dragcaret event by accessible caret. r=TYLin,smaug ... To support magnifying glass on GeckoView, I would like to add `dragcaret` event and, clientX and clientX in CaretStateChangedEvent chrome event. Actually, accessible caret fires `presscaret` and `releasecaret` when accessbile caret is pressed or released. But when dragging this caret, no chrome event is fired. Since magnifying glass listens to moving this caret, I would like `dargcaret` for GeckoView. Also, Users' dragging point is necessary to set better position of magnifying glass windows. So I also want client point of dragging point on `presscaret` and `dragcaret` event. This event and properties are on layout.accessiblecaret.magnifier.enabled=true, So this can be only for GeckoView.
