Allow node_pool and enable_autopilot together for custom service account and oauth scopes

[modax]

Reverts #4894 for node_config and implements workaround in a similar fashion for google_container_cluster node_pool attribute

Fixes hashicorp/terraform-provider-google#9505

I was unable to run acceptance tests. As of current base commit, linter was only complaining about files I did not modify.

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.

Release Note Template for Downstream PRs (will be copied)

container: allowed setting `node_pool.node_config.service_account` and `node_pool.node_config.oauth_scopes` at the same time as `enable_autopilot = true` for `google_container_cluster`. Respectively disallowed `node_config` as it does not work.

Your assigned reviewer will help review your code by:

• Ensuring it's backwards compatible, covers common error cases, etc.
• Summarizing the change into a user-facing changelog note.
• Passes tests, either our "VCR" suite, a set of presubmit tests, or with manual test runs.

You can help make sure that review is quick by running local tests and ensuring they're passing in between each push you make to your PR's branch. Also, try to leave a comment with each push you make, as pushes generally don't generate emails.

If your reviewer doesn't get back to you within a week after your most recent change, please feel free to leave a comment on the issue asking them to take a look! In the absence of a dedicated review dashboard most maintainers manage their pending reviews through email, and those will sometimes get lost in their inbox.

I did not touch any code related to this test. Maybe some accidental flake? I will sign CLA as soon as you confirm this PR might get merged eventually

[melinath]

TestAccComputeInstance_soleTenantNodeAffinities is currently failing on all PRs; however, because container cluster and the related node resources are fairly complicated, you will definitely need to (at a minimum) add a test to make sure that the proposed config actually works.

I don't see any particular reason this wouldn't be merged at this time.

Sure, I will try to implement a test soon and come back.

Great, thanks!

This is not really how we have to do this. The right field to use is cluster_autoscaling.auto_provisioning_defaults.service_account

[modax]

Ok, fair enough. Closing this PR in the hopes of #6733 being merged eventually
