ODS: Generate named accessors for raw attributes
Currently named accessors are generated for attributes returning a consumer
friendly type. But sometimes the attributes are used while transforming an
existing op and then the returned type has to be converted back into an
attribute or the raw getAttr needs to be used. Generate raw named accessor
for attributes to reference the raw attributes without having to use the string
interface for better compile time verification. This allows calling
blahAttr() instead of getAttr("blah").
Raw here refers to returning the underlying storage attribute.
