Add support for request & response clone

[ejizba]

Just mirroring the existing "clone" methods already supported in undici/fetch. Per the docs, "the main reason clone() exists is to allow multiple uses of body objects (when they are one-use only.)"

Fixes #207

@ejizba Thank you for adding this. Any chance this could be released to NPM?

Hi @restfulhead our plan is to do a release at the end of January, so should be out pretty soon

Hi @ejizba, thank for adding this will help us a lot.
it is possible to have an alpha build to start testing it? we are building some middleware and we didn't find a way to workaround this yet

[ejizba]

@Sarabadu You could download the tgz file from our latest v4.x branch build: https://azfunc.visualstudio.com/Azure%20Functions/_build/results?buildId=159678&view=artifacts&pathAsName=false&type=publishedArtifacts

(download "drop.zip", unzip that, and from your repo do npm install <path to azure-functions-4.1.0-alpha.20240111.3.tgz>)

@ejizba Any updates regarding the release?

Btw, the link https://azfunc.visualstudio.com/Azure%20Functions/_build/results?buildId=159678&view=artifacts&pathAsName=false&type=publishedArtifacts takes me to an almost empty page. I don't see any file to download.
