    Use tox-4 for linters and Molecules

    It removes following things:
    - skipdist option
    - updates whitelist_externals to allowlist_externals
    - Drops tox-bindep as it does not support tox-4
    - Tox-4 also includes fix for hanging issue:
      https://github.com/tox-dev/tox/issues/2595

    bindep is quite stable and tox-4 is around from long
    time and tox-bindep last got released on jan 2021. [1]
    https://github.com/tox-dev/tox-bindep/releases/tag/0.2.1

    So, We are dropping it.
