[PWGHF] Fix linting errors: struct member order and naming

- Move HfHelper, HfEventSelection, and ccdb declarations after all
  Configurable members in taskD0 and taskDplus (PWGHF struct member order)
- Rename UpcQaHistoConfig to HfUpcQaHistoConfig to comply with PWGHF
  naming convention (structs must start with Hf)
