Support Array BuildConfig

[sadeghbarati]

Describe the feature

Refrence:

• Rollup
• tsup

Currently unbuild ^1.2.0 defineBuildConfig support one BuildConfig not BuildConfig[]
unbuild expose an API called build to do things in a programmatic way,
But I prefer using build.config.ts file with unbuild cli instead of creating a script file like build.mjs

Additional information

I want to apply different configs per entry

Simple example

import { defineBuildConfig } from 'unbuild'

export default defineBuildConfig([
  {
    entries: 'src/index',
    replace: {
      __DEV__: `(process.env.NODE_ENV === 'development')`
    }
    rollup: {
      emitCJS: true
    }
  },
  {
    entries: 'src/index',
    outDir: 'dist/min',
    replace: {
      __DEV__: JSON.stringify(process.env.NODE_ENV === 'development')
    }
    rollup: {
      emitCJS: true,
      esbuild: {
        minify: true
      }
    }
  }
])

Advanced example

Pinia rollup.config

I like unbuild jiti¹ and hooks features, and I wonder how to convert that config to unbuild.config
