- pkg/declextract: move const handling logic from the clang tool
- pkg/declextract: remove unused includes and defines
Export raw info about consts from the clang tool, and let the Go part handle it. The less logic is in the clang tool, the better. Also this will allow to remove unused includes when we know which consts we ended up using. The more includes we include, the higher the chances we include something that's broken.
This is nice on its own, but this will also help to prevent lots of problems when we export more info from the clang tool in future. The clang tool does not know what will end up in the final descriptions, so it exports info about all consts that it encounters. As the result we pull in lots of includes/defines, and lots of kernel includes/defines are broken or create problems. So the fewer we have, the better.
