Add retries for modified services to google_project_service

[modular-magician]

Fixes hashicorp/terraform-provider-google#7103

This also fixes a minor bug with renamed services I spotted reading the logs- we actually only try the alternate name right now. Luckily that works!

If this PR is for Terraform, I acknowledge that I have:

• Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read the Release Notes Guide before writing my release note below.

serviceusage: added retries when a service is already being modified

serviceusage: fixed an issue where `bigquery.googleapis.com` was getting enabled as the `bigquery-json.googleapis.com` alias instead, incorrectly. This had no user impact yet, but the alias may go away in the future.
