[Accton][minipack3bta] Gate ACL byte counters by ASIC capability

Pre-submission checklist

• I've ran the linters locally and fixed lint errors related to the files I modified in this PR. You can install the linters by running pip install -r requirements-dev.txt && pre-commit install

Summary

• Configure ACL counters according to the ASIC ACL_BYTE_COUNTER capability.
• Use packet-only counters where byte counters are unsupported, while retaining packet and byte coverage on capable ASICs.
• Gate byte-stat reads and the counter-type transition test to avoid unsupported SAI operations.
