docs(turbopack): Migrate chunking docs from mdbook, with proof-reading and minor updates from claude (#91472)
Copied from https://turbopack-rust-docs.vercel.sh/turbopack/chunking.html
I had claude review it for correctness against the code. It found a few things where the names weren't correct or a trait was actually a struct, and it grouped things into sections. It also added some more details to a few sections, like the dev vs production chunking. I think this is a reasonable improvement.
I did a second pass with claude where I had it remove things it 1:1 duplicated with the existing rustdocs, and I had it add intradoc links.
