Add PYTHON3_SWSSCOMMON as build time dependency to Mellanox platform …

…API (#13847)

- Why I did it
Add PYTHON3_SWSSCOMMON as build time dependency to Mellanox platform API to avoid issue like:

19:34:11  ImportError while loading conftest '/sonic/platform/mellanox/mlnx-platform-api/tests/conftest.py'.
19:34:11  tests/conftest.py:28: in <module>
19:34:11      from sonic_platform import utils

19:34:11      from sonic_platform import *
19:34:11  sonic_platform/platform.py:28: in <module>
19:34:11      raise ImportError(str(e) + "- required module not found")
19:34:11  E   ImportError: No module named 'swsscommon'- required module not found- required module not found
19:34:11  [  FAIL LOG END  ] [ target/python-wheels/bullseye/mlnx_platform_api-1.0-py3-none-any.whl ]
The issue only happens when calling below command:

make target/python-wheels/bullseye/mlnx_platform_api-1.0-py3-none-any.whl
