The "layer" and "issuerLayer" rules are useful experimental properties that are currently stripped out by the Vue Loader plugin. This change fixes that issue.My specific use-case was to load SVG files as Vue components if they are imported into a script, but import them as URLs if I reference them in the CSS. Layers make this trivial:```module.exports = {  experiments: { layers: true },  module: {    rules: [      { test: /\.vue$/, loader: "vue-loader" },      { test: /\.vue$/, resourceQuery: /type=script/, layer: "script" },      { test: /\.[jt]s$/, layer: "script" },      {        test: /\.svg$/i,        oneOf: [          { loader: 'vue-svg-loader', issuerLayer: "script" },          { loader: 'file-loader' },        ],      },    ],  }};```
