dan 7ffacec8ef Add more realistic bench fixtures (#95807)
This adds more fixtures modeled after Flight payloads from real sites:

- Vercel Dashboard-like (very app-y)
- React Docs-like after App Router conversion (mostly MDX site)
- Vercel Blog-like (passing down data from CMS)

(Actual data is randomly generated with a seed)

These are simplifications but I tried to incorporate the originals'
corresponding quirks. Such as Vercel Dashboard having many client
components; syntax highlight with many small spans in React Docs; Vercel
Blog currently shipping a load of data unnecessarily on the index page.
(The last one is not ideal but I think we should actually benchmark
"bad" cases like this too so I kept that.)
