I don't know if I followed correctly what you're asking about, but these are helpers to manage discardable attributes. The idea is that for example the ROCDL dialect involves a discardable attribute with the key `rocdl.reqd_work_group_size`, and the associated Attribute must be a `DenseI32ArrayAttr`.
This feature will generate a helper for managing this discardable attribute on operations. The operations don't know anything about the attribute, it's a property of the dialect itself.
