Wagner Maciel b7f2a033df feat(dev-infra): exposed new rule 'component_benchmark' via dev_infra (#36434) 
* 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

Ng2 Next Benchmark

This benchmark uses the upcoming view engine for Angular, which moves more functionality from codegen into runtime to reduce generated code size.

As we introduce more runtime code, we need to be very careful to not regress in performance, compared to the pure codegen solution.

Initial results: size of Deep Tree Benchmark

File size for Tree benchmark template, view class of the component + the 2 embedded view classes (without imports nor host view factory):

                           | bytes | ratio | bytes (gzip) | ratio (gzip)

------------------------------ | ----- | ----- | ------------ | ------------ Source template + annotation | 245 | 1x | 159 | 1x Gen code (Closure minified) | 2693 | 11.9x | 746 | 4.7x New View Engine (minified) | 868 | 3.5x | 436 | 2.7x

Initial results: performance of Deep Tree Benchmark

Measured locally on a MacBook Pro.
