[Feature]: varlet cli config support use typescript

[nonzzz]

Feature request 🚀

Expected:

• Just a discussion. I think we can load .ts file. For more type safety.
• Export function defineConfig for javascript user.

Examples:

// varlet.config.js

import { defineConfig } from '@varlet/cli'

export default defineConfig({
 // will be implemented.
})

Others:

• I'm glad to do it. If you think it's useful.

ok i expect to implement the config file for the commonjs module

We have plans to refactor the cli into the target module as esm in the future. so don't go to support the ts config file.
So there is no need to support esm and ts configuration files for the time being

You can separate the command parsing part into bin.js, and expose the defineConfig method in index.js
