Subject: [PATCH bpf-next] selftests/bpf: merge most of test_btf into test_progs
Move almost 200 tests from test_btf into test_progs framework to be exercised
regularly. Pretty-printing tests were left alone in test_btf because they are
very slow and were not even executed by default with test_btf. Also, they seem
to break when moved under test_progs and I didn't want to spend more time on
figuring out why they broke, given we don't want to execute them all the time
anyway.
All the test_btf tests that were moved are modeled as proper sub-tests in
test_progs framework for ease of debugging and reporting.
No functional or behavioral changes were intended, I tried to preserve
original behavior as close to the original as possible. `test_progs -v` will
activate "always_log" flag to emit BTF validation log.
