libbpf: Add link-based API for tcx
Implement tcx BPF link support for libbpf.
The bpf_program__attach_fd() API has been refactored slightly in order to pass
bpf_link_create_opts pointer as input.
A new bpf_program__attach_tcx() has been added on top of this which allows for
passing all relevant data via extensible struct bpf_tcx_opts.
The program sections tcx/ingress and tcx/egress correspond to the hook locations
for tc ingress and egress, respectively.
For concrete usage examples, see the extensive selftests that have been
developed as part of this series.
