libbpf: hide and discourage inconsistently named getters
Move a bunch of "getters" into libbpf_legacy.h to keep them there in libbpf 1.0. See [0] for discussion of "Discouraged APIs". These getters don't add any maintenance burden and are simple alias, but they are inconsistent in naming. So keep them in libbpf_legacy.h instead of libbpf.h to "hide" them in favor of preferred getters ([1]). Also add two missing getters: bpf_program__type() and bpf_program__expected_attach_type().
