build(dev-infra): update package.json and :npm_package (#36434)

* Set up dev-infra's :npm_package to also contain benchmarking suite
* Add benchmarking deps to dev-infra's package.json
* Add a bazel workspace to dev-infra's package.json. This is so that when a
  project wants to use dev-infra's code and macros, they can just import the
  macros from their node_modules instead of loading it separately
