Split support in Vercel Serverless

The Vercel adapter builds to a single function by default. Astro 2.7 added support for splitting your build into separate entry points per page. If you use this configuration the Vercel adapter will generate a separate function for each page. This can help reduce the size of each function so they are only bundling code used on that page.

```js
// astro.config.mjs
import { defineConfig } from 'astro/config';
import vercel from '@astrojs/vercel/serverless';

export default defineConfig({
  output: 'server',
  adapter: vercel(),
  build: {
    split: true
  }
});
```
