Upstreams the fix from #73310, so we can remove that patch.
Remove `infback.c` which we stopped compiling after #79273.
The `OF` macro was also removed so I can drop the patch where I yell
at Gentoo developers.
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/`.

seem to call `deflate` with the problematic parameters, but the extent
of the vulnerability is not fully clear upstream yet.
