- remove POC tag and now the implementation is complete
- in this patch, AttributedBTFType is created as a subclass of AttributedType. This makes quite some changes in the codebase for processing or handling AttributedBTFType. Alternatively, we could amend existing AttributedType to have a StringRef to store btf_tag. We can discuss which way is better.
- I may have missed some testing. Let me know what I have missed and I can add them.
