[PATCH net-next] tools: ynl-gen: array-nest: support arrays of nests

[Jakub Kicinski <kuba@kernel.org>]

TC needs arrays of nests, but just a put for now.
Fairly straightforward addition.

Sorry for trickling out random changes, I need
396786af1cea ("tools: ynl-gen: Allow multi-attr without nested-attributes again")
to reach net-next before I post submsg support. Otherwise there
will be a conflict.
