refactor: reaplace zoomTo by scale

[LinStan]

Description

更新graphdiff中的同步图事件中的缩放行为

Motivation and Context

原本的同步行为中，采用了zoomTo的x6api。该api内部实现缩放时，会基于画布的client坐标参与计算，这个行为当你的画布并非100%占据当前区域时，会导致缩放行为并非严格基于预期缩放点。

x6 logic code:

  getComputedSize() {
    let w = this.options.width
    let h = this.options.height
    if (!NumberExt.isNumber(w)) {
      w = this.container.clientWidth
    }
    if (!NumberExt.isNumber(h)) {
      h = this.container.clientHeight
    }
    return { width: w, height: h }
  }

zoom(factor: number, options?: TransformManager.ZoomOptions) {
    options = options || {} 
    let sx = factor
    let sy = factor
    const scale = this.getScale()
    const clientSize = this.getComputedSize()
    let cx = clientSize.width / 2
    let cy = clientSize.height / 2
    //...
}

修复方式：
替换使用scale api实现准确的缩放逻辑
