chore(all): auto-regenerate .pb.go files (#646)

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.

fix: Don't include generator test protos in the API index.
  Keep `googleapis` and `googleapis-api-index-generator` separate when generating the API index.

  The index generator recurses down the directory structure... which means that test files in the generator's `test` directory are ending up being treated as APIs with a directory path of `gen/test/...`

  Fixes googleapis/googleapis-api-index-generator#18
