Modify the final webpack config

[Allenice]

What problem does this feature solve?

The vue-cli needs to provide a configuration that modifies the final webpack config before the webpack runs. For example, I need to customize the output file name when building the web component.

What does the proposed API look like?

// vue.config.js
module.exports = {
    finalWebpack: (config) => {
        return config
    }
}

I don't feel like adding this feature. It increases the cognitive burden for users and the maintenance burden for us maintainers, but brings little benefit.

• For common use cases, if there's any scenario that can't be supported with the current API interface, we should fix them case by case.
• For rare edge cases, users can opt-out Vue CLI and use webpack directly, using the resolved config object https://cli.vuejs.org/guide/webpack.html#using-resolved-config-as-a-file
