In Library Mode, I want to input entry path and Location to build from cli

Clear and concise description of the problem

I had been working on mono repo and want to build my whole project with the same vite.config.js
But what I will do is just change the scripts of package.json to achieve the dynamic results.

Suggested solution

"scripts": {
    "prettier": "prettier --write ./packages",
    "dev": "vite",
    "build": "vite build",
    "build:abc": "vite build --entry ./packages/abc/index.ts",
    "build:abcd": "vite build --entry ./packages/abcd/index.ts",
    "build:abcde": "vite build --entry ./packages/abcde/index.ts",
    "build:abcdef": "vite build --entry ./packages/abcdef/index.ts",
    "serve": "vite preview",
  },

I think it would be more robust if the Vite config support multiple entrypoints by default. Passing in the CLI directly is limited if we want to, say, output entries in different locations. This may be similar to #1736 and #4530. I'll close this in favor of the latter PR as it has more awareness.
