Add API config to allow disabling response size warning

[crice88]

Adds an API config option that disables warning a user when their API response body is over 4 megs. This has been added for users who'd like to stream larger amounts of data from their API acknowledging the drawbacks. This config mirrors the existing externalResolver config.

Closes: #33162

Thanks for the PR!

Would it be more reasonable to allow a custom threshold? Docs might need updating too – otherwise the feature is hidden.

Hold

#34700 (comment)

@crice88, The original implementation seems to already measure bytes?
https://github.com/vercel/next.js/pull/26831/files#diff-098f0eca63ed374378d9984a17c485bcfb01793e8f8b5bb82af4d15a28c2127bR75

Docs might need updating too – otherwise the feature is hidden.

Agreed

[crice88]

Added documentation as well as a way to customize the bodyLimit

[crice88]

Changed bodyLimit to responseLimit. Moved bytes underneath dev deps and added the reference to the pre compile step.
