feat: use @vue/compiler-sfc as a s compiler for TS if available

The `fork-ts-checker-webpack-plugin` is using `vue-template-compiler` by default, and this compiler is not the correct one to pick for vue-next. This commit tries to load `@vue/compiler-sfc` and falls back to `vue-template-compiler` if it does not find it.
