Security update, fixes CVE-2022-37434 in zlib. Only applications exposing/using `inflateGetHeader()` seem to be affected, which is not our case, so this is not critical for Godot. Remove duplicated copy of zlib in freetype sources to force using the updated version in `thirdparty/zlib/`. Co-authored-by: Rémi Verschelde <rverschelde@gmail.com> (cherry picked from commit 93409b8e64a9bc3c271ab4a7489b59a43bc0d048)
