What problem does this feature solve?

As a vue-cli and Vue 3 user I would like to be able to build and deploy a package as a web compomponent, so that it can be built and deployed in the same way as it's currently possible with vue-cli and Vue 2

What does the proposed API look like?

i.e. vue-cli-service build --target wc --name my-web-component-name --inline-vue
