selftests: forwarding: lib: Add tc_rule_handle_stats_get() 

The function tc_rule_stats_get() fetches a given statistic of a TC rule
given the rule preference. Another common way to reference a rule is using
its handle. Introduce a dual to the aforementioned function that gets a
statistic given rule handle.
