libbpf: Introduce bpf_object__btf
Add new accessor for bpf_object to get opaque struct btf * from it.
struct btf * is needed for all operations with BTF and it's present in
bpf_object. The only thing missing is a way to get it.
Example use-case is to get BTF key_type_id and value_type_id for a map in
bpf_object. It can be done with btf__get_map_kv_tids() but that function
requires struct btf *.
Similar API can be added for struct btf_ext but no use-case for it yet.
