Add a clang tidy check for filesystem path usage

[pifopi]

Add something like this

Checks: '-*,bugprone-forbidden-functions'
CheckOptions:

• key: bugprone-forbidden-functions.ForbiddenFunctions
  value: 'std::filesystem::path::path'
• key: bugprone-forbidden-functions.ForbiddenFunctionsMessage
  value: 'Direct construction of std::filesystem::path from std::string is banned due to Windows Unicode issues. Use XXXXX instead.'

Will be fixed by #1060
Clang tidy is wayyyy too slow as it more than double CI times
