qga/commands-win32: Do not set matrix_lookup_t/win_10_0_t arrays size

Browse source 
ga_get_win_name() iterates over all elements in the arrays by
checking the 'version' field is non-NULL. Since the arrays are
guarded by a NULL terminating element, we don't need to specify
their size:

  static char *ga_get_win_name(...)
  {
      ...
      const ga_matrix_lookup_t *table = WIN_VERSION_MATRIX[tbl_idx];
      const ga_win_10_0_t *win_10_0_table = ...
      ...
      while (table->version != NULL) {
                    ^^^^^^^^^^^^^^^
              while (win_10_0_table->version != NULL) {
                                     ^^^^^^^^^^^^^^^

This will simplify maintenance when adding new entries to these
arrays.

Split WIN_VERSION_MATRIX into WIN_CLIENT_VERSION_MATRIX and
WIN_SERVER_VERSION_MATRIX because  multidimensional array must
have bounds for all dimensions except the first.
