[turbopack] Support `experimental.serverMinification` & expand `experimental.turbopackMinify` (#96578)
Closes https://github.com/vercel/next.js/issues/96574.
Implements:
> experimental.turbopackMinify accepts per-environment granularity, e.g.
{ server: false, client: true } (restoring serverMinification parity)
I also added the edge runtime in there, even though it isn't too widely
used.
