Andrii Nakryiko 22ba363516 selftests/bpf: Move and extend ASSERT_xxx() testing macros ...

Move existing ASSERT_xxx() macros out of btf_write selftest into test_progs.h
to use across all selftests. Also expand a set of macros for typical cases.

Now there are the following macros:
  - ASSERT_EQ() -- check for equality of two integers;
  - ASSERT_STREQ() -- check for equality of two C strings;
  - ASSERT_OK() -- check for successful (zero) return result;
  - ASSERT_ERR() -- check for unsuccessful (non-zero) return result;
  - ASSERT_NULL() -- check for NULL pointer;
  - ASSERT_OK_PTR() -- check for a valid pointer;
  - ASSERT_ERR_PTR() -- check for NULL or negative error encoded in a pointer.
