selftests/bpf: Add tests for ldsx of pkt data/data_end/data_meta accesses
The following tests are added to verifier_ldsx.c:
- sign extension of data/data_end/data_meta for tcx programs.
The actual checking is in bpf_skb_is_valid_access() which
is called by sk_filter, cg_skb, lwt, tc(tcx) and sk_skb.
- sign extension of data/data_end/data_meta for xdp programs.
- sign extension of data/data_end for flow_dissector programs.
All newly-added tests have verification failure with message
"invalid bpf_context access". Without previous patch, all these
tests succeeded verification.
