bpf: make it easier to add new metadata kfunc
No functional changes.
Instead of having hand-crafted code in bpf_dev_bound_resolve_kfunc,
move kfunc <> xmo handler relationship into XDP_METADATA_KFUNC_xxx.
This way, any time new kfunc is added, we don't have to touch
bpf_dev_bound_resolve_kfunc.
Also document XDP_METADATA_KFUNC_xxx arguments since we now have
more than two and it might be confusing what is what.
