tools/bpf: Sync btf_ids.h to tools
Sync kernel header btf_ids.h to tools directory. Also define macro CONFIG_DEBUG_INFO_BTF before including btf_ids.h in prog_tests/resolve_btfids.c since non-stub definitions for BTF_ID_LIST etc. macros are defined under CONFIG_DEBUG_INFO_BTF. This prevented test_progs from failing.
