[feat] Need js api appWindow.startMoving

[zkip]

Describe the problem

Add new api "startMoving" to support more free moving windows.

Describe the solution you'd like

I want to implement right-click dragging of the window, just like PureRef. but after I call appWindow.startDragging by right-clicking, then I find that I must press the left mouse button before dragging the window. I can't think of any other ways implementate this.
Maybe there is an api called "startMoving", which will immediately make the window follow the mouse position without clicking the mouse.
In addition, this not only allows "right-click dragging", but also allows the window to be dragged at any time, such as pressing a certain button to drag, etc.
