This will be used as the foundation for writing a list of MinidumpUTF8String objects. MinidumpUTF8String (and UTF-16 MINIDUMP_STRING) objects are never referenced by MINIDUMP_LOCATION_DESCRIPTOR because they carry their own lengths. Instead, they are always referenced by RVA. The list of MinidumpUTF8String objects will be used for the module annotations vector.
