meson: Improve search for libpng

On Visual Studio-style builds, it is likely that we do not have pkg-config
files for libpng, so improve the search for libpng by using CMake's built-in
mechanisms for looking for libpng.  This, however, means that we need to use
'png' rather than 'libpng' for the package name to search for.
