David Peter fedd982fd5 [red-knot] Avoid unresolved-reference in unreachable code (#17169) ...

## Summary

This PR changes the inferred type for symbols in unreachable sections of
code to `Never` (instead of reporting them as unbound), in order to
silence false positive diagnostics. See the lengthy comment in the code
for further details.

## Test Plan

- Updated Markdown tests.
- Manually verified a couple of ecosystem diagnostic changes.
