reverseproxy: Sync up handleUpgradeResponse with stdlib (#4664)
* reverseproxy: Sync up `handleUpgradeResponse` with stdlib

I had left this as a TODO for when we bump to minimum 1.17, but I should've realized it was under `internal` so it couldn't be used directly.

Copied the functions we needed for parity. Hopefully this is ok!

* Add tests and fix godoc comments
