firewall: optimize DNAT rules and skip invalid rules and redirects (#14485)

	- instead of writing one (or more) ACCEPT rules in the filter table
	  for each redirect install a global ctstate DNAT accept rule per zone

	- discard rules and redirects which have invalid options set instead
	  of silently skipping the invalid values
