wait for instance status only after create/update

[ScottSuarez]

closes hashicorp/terraform-provider-google#9631

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.

compute: changed `wait_for_instances` in `google_compute_instance_group_manager` and `google_compute_region_instance_group_manager` to no longer block plan / refresh, waiting on managed instance statuses during apply instead

Your changelog entry is out of date now, right? I'd suggest something user-focused eg:

compute: changed `wait_for_instances` in `google_compute_instance_group_manager` and `google_compute_region_instance_group_manager` to no longer block plan / refresh, waiting on managed instance statuses during apply instead
