bpf: net_sched: Add basic bpf qdisc kfuncs
Add basic kfuncs for working on skb in qdisc.
Both bpf_qdisc_skb_drop() and bpf_kfree_skb() can be used to release
a reference to an skb. However, bpf_qdisc_skb_drop() can only be called
in .enqueue where a to_free skb list is available from kernel to defer
the release. bpf_kfree_skb() should be used elsewhere. It is also used
in bpf_obj_free_fields() when cleaning up skb in maps and collections.
bpf_skb_get_hash() returns the flow hash of an skb, which can be used
to build flow-based queueing algorithms.
Finally, allow users to create read-only dynptr via bpf_dynptr_from_skb().
