Eclipse Californium (Cf) CoAP Framework 4.0.0-M3

The milestone release 4.0.0-M3 comes with further cleanups and better support for systems using anonymous clients.

Some dependencies have been update, namely netty.io (see CVE-2025-24970) and the aws.sdk.

It also supports draft-ietf-tls-keylogfile for easier usage with WireShark.

If java 21 is used for runtime, it also adds support socket handling with java's virtual threads. That reduces the resources when a larger number of clients are emulated. It will still requires the resources for an UDP socket, so this shift the limit from 5000-1000 upto 30000-40000.
