ENH: support surfaceFieldValue on multiple faceZones or patches (#1874)

- additional "names" entry to specify a word/regex list of selections
  For example,
  {
      type    patch;
      name    inlets;
      names   ("inlet_[0-9].*" inlet);
  }

- if "names" exists AND contains a literal (non-regex) that can be used
  as a suitable value for "name", the "name" entry becomes optional.
  For example,
  {
      type    patch;
      names   ("inlet_[0-9].*" inlet);

      // inferred name = inlet
  }

- reduce some overhead in surfaceFieldValue
