trigger: introduce firing policies

A firing policy controls the rate of firing of a trigger.

Two firing policy mode are implemented:
    LTTNG_TRIGGER_FIRING_POLICY_FIRE_EVERY_N
       The triggers's actions are executed every N times the
       condition occurs.
    LTTNG_TRIGGER_FIRING_POLICY_ONCE_AFTER_N
       The triggers's actions are executed once the condition was met N
       times.

Firing policies will be moved to the specific `action` objects
in a follow-up commit as not all actions can implement the firing
policies.
