feat: 新增触发重新渲染事件ICE_RERENDER

[bloody-ux]

当前stream-error插件能够解决正常加载ice相关js的场景（通过script标签加载）。 但很多场景下，为了更好地渲染性能，业务测会通过createElement('script')方式异步加载ice的js， 这种情况下，很大概率load事件的触发会比 ice相关js加载完成更早完成，此时就没有办法做兜底rerender了。

PR中，新增一个window事件ICE_RERENDER，业务测在通过createElement('script')加载完成之后，dispatch一个ICE_RERENDER事件到window上，进行触发。

同时为了避免race condition，在PR中新增了hasRendered状态位，保证最多只会被触发一次。

版本号和Changelog的变更，请@ClarkXia帮忙变更
