compiler-sfc： 解析Scss时实现处未支持异步的情况，前面的API调用都已经支持了异步，但是实现的时候却只处理了同步的情况， 是否考虑在实现处支持promise的情况

What problem does this feature solve?
最近在做一些关于移植到浏览器内支持vue-sfc-loader时，浏览器内的scss.js 仅支持异步函数解析，处理到这块会出现问题，是否要增加代码适配scss异步的情况
What does the proposed API look like?
if（options.isAsync）{
result = await new Promise((resolve, reject) => {
nodeSass.render(finalOptions, (err, res) => { // node-scss 官方的语法， 浏览器内也只要实现一遍render方法即可
resolve(res)
})
})
} else{
result = nodeSass.renderSync(finalOptions)
}
