netfilter: nf_tables: consolidate set description

[ Upstream commit bed4a63ea4ae77cfe5aae004ef87379f0655260a ]

Add the following fields to the set description:

- key type
- data type
- object type
- policy
- gc_int: garbage collection interval)
- timeout: element timeout

This prepares for stricter set type checks on updates in a follow up
patch.
