Fix mCODE content profile paths
Fix mCODE content profile paths

Fix paths in the content profile.  Most fixes fall under one of these categories
- paths used parent type name instead of constrained type name (e.g., SubjectOfRecord instead of PatientSubjectOfRecord)
- paths referred to fields that didn't exist at all (e.g., CancerStageSuffix)
- paths referred to include types (e.g., DNARegionName)
- paths referred to nested fields that weren't mapped (e.g., Person.Race.RaceCode)
