feat(dev-infra): exposed new rule 'component_benchmark' via dev_infra (#36434)

Browse Source 
* Move tools/brotli-cli, tools/browsers, tools/components,
  tools/ng_rollup_bundle, and modules/e2e_util to dev-infra/benchmarking
* Fix imports and references to moved folders and files
* Set up BUILD.bazel files for moved folders so they can be packaged with
  dev-infra's :npm_package
