selftests/bpf: samples/bpf: Split off legacy stuff from bpf_helpers.h
Split off few legacy things from bpf_helpers.h into separate bpf_legacy.h file: - load_{byte|half|word}; - remove extra inner_idx and numa_node fields from bpf_map_def and introduce bpf_map_def_legacy for use in samples; - move BPF_ANNOTATE_KV_PAIR into bpf_legacy.h. Adjust samples and selftests accordingly by either including bpf_legacy.h and using bpf_map_def_legacy, or switching to BTF-defined maps altogether.
