feat(semantic): add "did you mean?" suggestions to undefined name errors (#19102)

## Improve `undefined_export` and related errors with name suggestions

This PR adds helpful "did you mean?" suggestions to errors where names are not found, using Levenshtein distance (threshold=2).

### Example Output

**undefined_export with suggestion:**
```
Export 'myVarible' is not defined
help: Did you mean 'myVariable'?
```

**private_field_undeclared with suggestion:**
```
Private field '#privateFild' must be declared in an enclosing class
help: Did you mean '#privateField'?
```

**invalid_label_target with suggestion:**
```
Use of undefined label
help: Did you mean 'outerLoop'?
```

### Implementation Details

- Moved Levenshtein edit distance calculation from `oxc_linter` to `oxc_span` for reuse across crates
- Uses a threshold of 2 for edit distance to suggest similar names
- Collects available names from appropriate scopes only when errors are found (performance optimization)
