Make chip::Logging::GetModuleName public (#26664)

* Make chip::Logging::GetModuleName public

Problem:
- Platform LogV receives the module name string
- To make any choices based on module, the module names
  must be visible
- Somehow the module names getter was not public

This PR:
- Make the function public (no functional change)

Testing done:
- Still builds, unit tests pass

* Restyled by clang-format
