Transforms: Extract Fields: Remove Deduplication feature toggle (#113709)

Remove extractFieldsNameDeduplication feature toggle

The extractFieldsNameDeduplication feature has reached GA (General Availability),
so the feature toggle is no longer needed. The name deduplication behavior is
now permanently enabled.

Changes:
- Removed feature toggle definition from registry.go
- Removed feature toggle check in extractFields.ts (always deduplicate now)
- Updated tests to remove feature toggle manipulation
- Regenerated feature toggle files
