Pass configOptions to environment setup

Clear and concise description of the problem

When @vitest-environment-options is specified in a test file, those options are passed to the custom environment's setup method.

With access to the environmentOptions defined in the config, custom environments would be able to override specific options on a per-test basis, which would make @vitest-environment-options more flexible.

Thank you for the guidance in the pull request🙏

Suggested solution

How about passing configOptions as an additional parameter to setup and setupVM ?

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that requests the same feature to avoid creating a duplicate.

Start by locating the custom environment setup and setupVM entry points, then trace how @vitest-environment-options and configured environmentOptions are currently handled. Add coverage for the configOptions parameter and verify that config-defined options can be overridden per test without breaking existing environment setup behavior.
