openvmm/ttrpc/repl: Extend ttrpc interface and repl command list to support bind/unbind requests for consommé

[damanm24]

This PR builds on top of the work done in #3364 by extending OpenVMM's ttrpc interface to include port-forwarding commands. I also ended up adding the bind/unbind port commands to OpenVMM's REPL command list when testing the changes.

Pull request overview

Extends the Consomme networking backend to support runtime port-forward bind/unbind requests (via a mesh channel), and wires this capability into OpenVMM’s ttrpc VMService API and the interactive REPL so ports can be managed after VM creation.

Changes:

• Add a cross-proc Consomme port request channel (ConsommeRequest) and plumb it through ConsommeHandle to the net_consomme endpoint.
• Update net_consomme to handle initial port forwards plus runtime bind/unbind requests (creating/binding host sockets on demand).
• Extend the ttrpc proto and OpenVMM REPL command set to expose bind/unbind operations.
