Tooling to accept payload size changes

[AndrewKushnir]

Currently in the angular/angular repo, when a change affects payload size for integration test app or AIO, an error is thrown on CI (example CI failure):

FAIL: Commit undefined uncompressed main fell below expected size by 500 bytes or >1% (expected: 231381, actual: 230780).
If this is a desired change, please update the size limits in file '../.cache/bazel/_bazel_circleci/9ce5c2144ecf75d11717c0aa41e45a8d/execroot/angular/bazel-out/k8-fastbuild/bin/integration/cli-hello-world-lazy/test.sh.runfiles/angular/goldens/size-tracking/integration-payloads.json'.

We have a number of test apps (~10) for which we track payload size, thus it takes time to manually update everything. Also, minor payload size deltas between the main and a patch branches causes issues during the merge (when merge is requested to both main and patch branches), thus engineers end up creating a new PR and re-do all the manual updates to payload sizes once again.

It'd be great if we can have a tooling to update payload sizes, similar to what we have for tracking the symbols (via yarn symbol-extractor:update). That'd improve the quality of life for us, reduce CI reruns and save a bunch of time.

Also, I noticed that the payload size error for each app is present in the CI output more than once. Do we run it multiple times for some reasons?
