Filter unconfigured ports buffers queue/pg counters configurations on init.
If no buffer configurations available, no counters will be created.
Allow creating/removing counters on runtime if buffer PG/Queue is created or removed.
New UT added to verify new flow.

What I did Currently, in SONiC all ports queue and pg counters are created by default with the max possible amount of counters. This feature changes this behavior to poll only configured counters provided by the config DB BUFFER_PG and BUFFER_QUEUE tables. If no tables are present in the DB, no counters will be created for ports. Filter the unwanted queues/pgs returned by SAI API calls and skip the creation of these queue/pg counters. Also, allow creating/removing counters on runtime if buffer PG/Queue is configured or removed.
Why I did it Improve performance by filtering unconfigured queue/pg counters on init.
How I verified it Check after enabling the counters, if configured counters are created in Counters DB according to the configurations. Add/Remove buffer PG/Queue configurations and observe the corresponding counters created/removed accordingly. New UT was added to verify this flow.
