HCD-96: Upgrade Netty to 4.1.118.Final

[emerkle826]

This patch updates Netty to address CVE-2025-24970.
It also adds the Netty native epoll dependency
that was missing when Netty was upgraded from
4.1.58 to 4.1.117. Since 4.1.58, the native
libraries are now separated out into new dependencies
and must be explicitly added for them to be bundled into the tarball.

What is the issue

When Netty was upgraded to 4.1.117.Final, the native epoll libraries that used to be shipped in the netty-all.jar were not included. At some point since Netty 4.1.58, the native epoll and native kqueue libraries were split inot their own architecture dependent jarfiles/artifacts and must be included explicitly to pick them up.

What does this PR fix and why was it fixed

This patch adds the missing native epol dependencies. This is similar to what was done in OSS Cassandra when they upgraded to Netty 4.1.96 here:
