Merge bitcoin/bitcoin#24675: util: Use ArgsManager::GetPathArg more widely

b01f336708 util, refactor: Drop explicit conversion to fs::path (Hennadii Stepanov)
138c668e2b util, refactor: Use GetPathArg to read "-rpccookiefile" value (Hennadii Stepanov)
1276090705 util, refactor: Use GetPathArg to read "-conf" value (Hennadii Stepanov)

Pull request description:

  This PR is a continuation of bitcoin/bitcoin#24265 and bitcoin/bitcoin#24306.

  Now the following command-line arguments / configure options been read with the `GetPathArg` method:
  - `-conf`, also `includeconf` values been normalized
  - `-rpccookiefile`
