fix Qt macOS build with Clang 18
See:
https://github.com/pnggroup/libpng/commit/893b8113f04d408cc6177c6de19c9889a48faa24.
In a similar manner as zlib (madler/zlib#895),
libpng contains a header configuration that's no longer valid and
hasn't been exercised for the macOS target.
- The target OS conditional macros are misused. Specifically
`TARGET_OS_MAC` covers all Apple targets, including iOS, and it
should not be checked with `#if defined` as they would always be
defined (to either 1 or 0) on Apple platforms.
- `#include <fp.h>` no longer works for the macOS target and results
in a compilation failure. macOS ships all required functions in
`math.h`, and clients should use `math.h` instead.
