Bazel files are not updated automatically. Updating them in the same commit is fine (but not required).

GN files are updated by the GN syncbot (e.g. a40b36f28e184adec975b682bc8d0fbeeb91113e), but needs manual intervention from time to time. I assume it's _probably_ the same as Bazel, i.e. fine to update them in the same commit. At any rate, GN and Bazel are both in the same peripheral tier -- if the change you've made to either GN or Bazel is incorrect, that's fine; someone who's invested in GN or Bazel will fix it later.
