Packaging: add octez-dal-node package (post-19.1 packages)

What

Add Debian packages for the DAL node. As other packages, we propose a minimal configuration to the user.

The configuration options are in /etc/defaults/octez-dal-node.

Why

It's the third MR following !11693 (merged) and !12020 (merged).

How

Manually testing the MR

To test these packages, you should have already a L1 stack available using the post-v19.1 packages. you can check this document on how to setup a complete L1 stack : https://hackmd.io/qwid55dJSd6R6AnvcyEKKQ?view

Then you can try to install the DAL package, enable the systemd service and run the node.
