use server component transform for segment validation (#72051)
After adding validation that fixing invalid segment configs (when DIO is
enabled), it revealed that errors weren't being displayed in Turbopack,
because `setHMRServerError` wasn't implemented.
This refactors the implementation to use the existing server component
transform when validating if the segments are valid. This has the
benefit of highlighting precisely where the segment is coming, making it
easier to remove. The test that was skipped in Turbopack is also
re-enabled.
