FindTIFF: Restore support for projects that do not enable CMP0057

Since commit 6a3059e66f (FindTIFF: bridge `tiff-config` into
FindTIFF-compatible interface, 2023-09-14, v3.28.0-rc1~87^2) we use the
`if(IN_LIST)` test that required CMP0057.  Expand the scope over which
we enable that policy explicitly.

Issue: #25485
