Add selftests validating BTF deduplication for split BTF case. Add a helper
macro that allows to validate entire BTF with raw BTF dump, not just
type-by-type. This saves tons of code and complexity.

selftests/bpf: Add checking of raw type dump in BTF writer APIs selftests2020-11-06T02:37:30ZAndrii Nakryikoandriin@fb.com2020-11-05T04:33:56Zurn:sha1:1306c980cf892bc17e7296d3e9ab8e9082f893a1
Add re-usable btf_helpers.{c,h} to provide BTF-related testing routines. Start
with adding a raw BTF dumping helpers.
Raw BTF dump is the most succinct and at the same time a very human-friendly
way to validate exact contents of BTF types. Cross-validate raw BTF dump and
writable BTF in a single selftest. Raw type dump checks also serve as a good
self-documentation.
