IMPALA-14134: Switch to newer versions of zlib / cloudflare zlib

This moves from zlib 1.2.13 to zlib 1.3.1 and bumps cloudflare
zlib to a newer version. This does not require any update to the
toolchain, because these newer versions were already present.

Testing:
 - Ran a perf-AB-test with no major difference in performance

> Impala currently uses zlib 1.2.13, but zlib 1.3.1 has been shipped and is 
> already in the native-toolchain. Similarly, there is a newer version of 
> cloudflare zlib available in the toolchain. We should upgrade and stop using 
> those older versions.
