New input to control activation/deactivation of chart auto-resize feature

[arethore-actility]

I'm working on an app where the chart auto-resize feature is conflicting with the rendering of other components when toggling from/to fullscreen view.
I'd like to be able to control whether or not this auto-resize feature is activated.

I propose to add an 'autoResize' input in NgxEchartsDirective, controlling the activation of the auto-resize feature triggered by a window resize event.
Of course, by default, the automatic resize feature is activated (autoResize = true).

Thanks. It's useful.

這個 autoResize 只有在視窗改變大小的時候會觸發，但是 div container 改變大小時不會觸發，例如在使用側邊欄(sidenav)的情況下，圖表不會隨 sidenav 的開闔自動 resize

@covera Yes, you should handle the case manually.
