    [SHELL32] Add the handy WHICH_DEFAULT value to the list of flags in shlwapi_undoc.h.
    
    - Add as well the undocumented 0x40 dwFlags value from
shlwapi!PathFileExistsDefExtW()
      to the list.
    
    - Fix a bug (also present in Win2k3) in PathResolveW() where, specifying
      the PRF_DONTFINDLNK flag, would also erroneously exclude checking for
      the .cmd extension as well (which was obviously NOT the original
      intention, from the name of the flag and the documentation as well:
     
https://docs.microsoft.com/en-us/windows/win32/api/shlobj_core/nf-shlobj_co…
      ).
    
    Addendum to 3a822e4f.
