Remove functions-related buildpacks

The `heroku/nodejs-function-invoker`, `heroku/nodejs-npm`, and `heroku/nodejs-function` buildpacks have been split out to their own [maintenance branch](v3.6.3...sf-functions). The reason for this is so that Node.js Function CNBs can be isolated from future changes to the buildpacks on `main`.
