live2d-widget Migrate to pixi-live2d-display

The built-in live2d.min.js only supports Live2D v2.1 models. This PR migrates to the pixi-live2d-display library to add support of Live2D v3 models, and the models will be rendered to the canvas with PixiJS v5.

This PR also includes a bugfix that the model can't be loaded when there is only one model in the list.

@PFiS1737 把错误贴出来看看？

我发这个PR是因为我这边用的模型是V3的，查了一下资料发现这个repo里的live2d.min.js是2.1版本的。

@PFiS1737 autoload.js需要放在其他几个依赖script的后面。

@qingchenling 你这个看起来是网络错误，到Chrome Dev Tools里的Network看看吧。

@perqin 我觉得不太像，后台 api 的 get 报错了

<br />
<b>Warning</b>:  file_get_contents(../model/AZ/lafei/index.json): Failed to open stream: No such file or directory in <b>C:\inetpub\wwwroot\test\live2d_api\get\index.php</b> on line <b>22</b><br />
<br />
<b>Warning</b>:  Trying to access array offset on value of type null in <b>C:\inetpub\wwwroot\test\live2d_api\get\index.php</b> on line <b>29</b><br />
<br />

{
    "model": "../model/AZ/lafei/"
}

没有 index.json，但是我看 moc3 模型中没有这个文件，我在想是我模型的格式不对，还是说后台 api 的 get 也需要改。。。~~（如果也要改，那菜菜的我就不会力）~~
