SDL_hidapi_ps4.c: define NTDDI_VISTA / _WIN32_WINNT_VISTA if not defined

it still needs a Vista or newer Platform SDK to build, though.

    67  *
    68  * Get the "pref dir". This is meant to be where users can write personal
    69  *  files (preferences and save games, etc) that are specific to your
    70  *  application. This directory is unique per user, per application.
    71  *
    72  * This function will decide the appropriate location in the native filesystem,
    73  *  create the directory if necessary, and return a string of the absolute
    74  *  path to the directory in UTF-8 encoding.
    75  *
    76  * On Windows, the string might look like:
    77  *  "C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name\\"
    78  *
    79  * On Linux, the string might look like:

    82  * On Mac OS X, the string might look like:

    88  *  your name or an Internet domain you own might do) and the name of your
    89  *  application. These should be untranslated proper names.
    90  *
    91  * Both the org and app strings may become part of a directory name, so
    92  *  please follow these rules:
    93  *
    94  *    - Try to use the same org string (including case-sensitivity) for
    95  *      all your applications that use this function.
    96  *    - Always use a unique app string for each one, and make sure it never
    97  *      changes for an app once you've decided on it.
    98  *    - Unicode characters are legal, as long as it's UTF-8 encoded, but...
    99  *    - ...only use letters, numbers, and spaces. Avoid punctuation like
   100  *      "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
   101  *
   102  * This returns an absolute path in UTF-8 encoding, and is guaranteed to
   103  *  end with a path separator ('\\' on Windows, '/' most other places).
   104  *
   105  * The pointer returned by this function is owned by you. Please call
   106  *  SDL_free() on the pointer when you are done with it, or it will be a
   107  *  memory leak. This is not necessarily a fast call, though, so you should
   108  *  call this once near startup and save the string if you need it.
   109  *
   110  * You should assume the path returned by this function is the only safe
   111  *  place to write files (and that SDL_GetBasePath(), while it might be
   112  *  writable, or even the parent of the returned path, aren't where you
   113  *  should be writing things).
   114  *
   115  * Some platforms can't determine the pref path, and on other
   116  *  platforms, this might be meaningless. In such cases, this function will
   117  *  return NULL.
   118  *
   119  *   \param org The name of your organization.
   120  *   \param app The name of your application.
