net/mlx5: fs, add API for sharing HWS action by refcount

Browse source

Counters HWS actions are shared using refcount, to create action on
demand by flow steering rule and destroy only when no rules are using
the action. The method is extensible to other HWS action types, such as
flow meter and sampler actions, in the downstream patches.

Add an API to facilitate the reuse of get/put logic for HWS actions
shared by refcount.
