feat(all): auto-regenerate .pb.go files (googleapis#505)

This is an auto-generated regeneration of the .pb.go files by
cloud.google.com/go/internal/gapicgen. Once this PR is submitted, genbot will
update the corresponding PR to depend on the newer version of go-genproto, and
assign reviewers. Whilst this or any regen PR is open in go-genproto, genbot
will not create any more regeneration PRs. If all regen PRs are closed,
gapicgen will create a new set of regeneration PRs once per night.

If you have been assigned to review this PR, please:

- Ensure that CI is passing. If it's failing, it requires your manual attention.
- Approve and submit this PR if you believe it's ready to ship. That will prompt
genbot to assign reviewers to the google-cloud-go PR.

- chore(analytics/admin): Make microgenerators default for all languages

  In particular this applies to Java and Python microgenerators.
  With this change `java_gapic_*` and `py_gapic_*` rules mean microgenerator versions. The monolith versions of the rules are named as `java_gapic_*_legacy` and `py_gapic_*_legacy` respectively.

  Also change Ads BAZEL template to reflect the change in default rule names.

  Also change `DO NOT OVERRIDE` comment warnings meaning (to reflect that now by default microgenerator rules are generated and the generated version must be accepted only if the API is being migrated to the microgenerator).
