Move some handwritten acc tests to service package

[zli82016]

As we don't want to move all of the tests in one PR. The PR 8272 is going to be split into two PRs. This is the first PR.

1. Move handwritten tests to the specific service packages
2. Move function ServiceAccountCanonicalEmail to the envvar package
3. Move function GetResourceAttributes to the tpgresource package

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).
• 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).
• Generated Terraform providers, and ran make test and make lint in the generated providers to ensure it passes unit and linter tests.
• Ran relevant acceptance tests using my own Google Cloud project and credentials (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read Write release notes before writing my release note below.
