4a1b510f - Add more test cases to the `dynamicIO` sync IO access test suite (#81045)

Add more test cases to the `dynamicIO` sync IO access test suite (#81045) With this PR, we're adding test fixtures for `headers()`, `draftMode()`, and (fallback) `params`, by more or less copy&pasting the fixture for `cookies()`. We're also adding assertions for environment prefixes of `console.log()` calls that happen after the sync IO access.
