tools: ynl-gen: introduce support for bitfield32 attribute type
Introduce support for attribute type bitfield32.
Note that since the generated code works with struct nla_bitfield32,
the generator adds netlink.h to the list of includes for userspace
headers in case any bitfield32 is present.
Note that this is added only to genetlink-legacy scheme as requested
by Jakub Kicinski.
