zlib: import zlib-1.3.1

2025-07-31T13:25:15+00:00

This is vanilla zlib-1.3.1 imported over the existing zlib/ dir with:
* README adjusted to add the GCC note at the top;
* GCC's ChangeLog merged with the upstream one, as before;
* Deleted upstream Makefile as has been done before (we use an autoconf-
  generated one)
