[wrangler] Add bundle sizes to structured output

[longlho]

wrangler deploy --dry-run currently reports bundle size only through human-formatted console output. CI size gates must regex that text, which is brittle.

This adds exact raw and gzip-compressed byte counts to the existing structured deploy and version-upload output records, including dry runs:

{
  "bundle_size": {
    "raw_bytes": 1234,
    "gzip_bytes": 567
  }
}

The bundle reporter now returns the measurements it already calculates, and deploy helpers pass them to Wrangler's output writer.

  • Documentation not necessary because: this extends Wrangler's existing machine-readable output without changing CLI usage.
