[cli] Store build error in "builds.json" file in vc build (#8148)

Browse Source 
When a build fails, store the serialized Error in the "builds.json" file under the "build" object of the Builder that failed.

Example:

```json
{
  "//": "This file was generated by the `vercel build` command. It is not part of the Build Output API.",
  "target": "preview",
  "argv": [
    "/usr/local/bin/node",
    "/Users/nrajlich/Code/vercel/vercel/packages/cli/src/index.ts",
    "build",
    "--cwd",
    "/Users/nrajlich/Downloads/vc-build-next-repro/"
  ],
  "builds": [
    {
      "require": "@vercel/next",
      "requirePath": "/Users/nrajlich/Code/vercel/vercel/packages/next/dist/index",
      "apiVersion": 2,
      "src": "package.json",
      "use": "@vercel/next",
      "config": {
        "zeroConfig": true,
        "framework": "nextjs"
      },
      "error": {
        "name": "Error",
        "message": "Command \"pnpm run build\" exited with 1",
        "stack": "Error: Command \"pnpm run build\" exited with 1\n    at ChildProcess.<anonymous> (/Users/nrajlich/Code/vercel/vercel/packages/build-utils/dist/index.js:20591:20)\n    at ChildProcess.emit (node:events:527:28)\n    at ChildProcess.emit (node:domain:475:12)\n    at maybeClose (node:internal/child_process:1092:16)\n    at Process.ChildProcess._handle.onexit (node:internal/child_process:302:5)",
        "hideStackTrace": true,
        "code": "BUILD_UTILS_SPAWN_1"
      }
    }
  ]
}
```
