Add a new .check_hooks interface for checking if the match/target is
used from the validate hook according to its configuration.
Move existing conditional hook check based on the match/target
configuration from .checkentry to .check_hooks for the following
matches/targets:
- addrtype
- devgroup
- physdev
- policy
- set
- TCPMSS
- SET
This is a preparation patch to fix nft_compat, not functional changes
are intended.
Based on patch from Florian Westphal.
