[DASH] Add support for ENI counters

[vivekrnv]

What I did

Depends on https://github.com/sonic-net/sonic-sairedis/pull/1418

• Added support for ENI Counters
• Refactored Flex Counter VS test to move the common infra logic and re-use in the dash vs tests

Why I did it

How I verified it

• Add a VS test
• Test Counters creation in VS Setup

Enable Flex Counter Creation:

<Enable FC for ENI>
sonic-db-cli CONFIG_DB HSET "FLEX_COUNTER_TABLE|ENI" FLEX_COUNTER_STATUS enable

<Check the FC Group Entry>
sonic-db-cli FLEX_COUNTER_DB HGETALL FLEX_COUNTER_GROUP_TABLE:ENI_STAT_COUNTER
{'POLL_INTERVAL': '10000', 'STATS_MODE': 'STATS_MODE_READ', 'FLEX_COUNTER_STATUS': 'enable'}

<Check the Counter ID list>
sonic-db-cli FLEX_COUNTER_DB HGETALL FLEX_COUNTER_TABLE:ENI_STAT_COUNTER:oid:0x76000000000027
