479 WIP - refactor net 8.0

[clouths]

This PR contain a refactor of the way you setup the project using docker compose.
There is a container for the asset which is a submodule of OPResource.
There is a container for the db which is a submodule of OPDB.
There is a container for the server using the files from this repository.

Changes:

• Add submodules for the asset and the db
• Add basic docker compose setup
• Add Makefile to help start/stop/restart/log containers
• convert the project to net 8.0 (thanks Fratakal)
• replace System.Drawing with SkiaSharp for linux support
• refactor database access for linux support

Hey!
You can check my fork. It is already migrated to Net8 and does work fine so far.
Release build is running localy without issues since 4 days or so.

What was done :

• Basically it update all the csproj (correct the Perpetuum.server, that was a bit broken if I remeber correctly)
• Update all dependency add some (For console command arg that microsoft stoped supporting, I was not willing to change too much code)
• Change the memorystream binary parsing that was considered unsafe therefore generated an error => changed for a simpler newtonsoft parsing.

You can use it.
or I can start a PR.

BTW
I'm too lazy *look shiny code there !* to copy/paste file correctly into the server folder publish Admintool & Server work like a charm

The purpose of moving the code to .NET is, in the future, to move to the Linux platform. Thanks for the message, I looked into your fork. For launching on Windows OS, your changes are quite suitable, but for migration to Linux additional changes are needed. They are mainly related to the work of database access and the lack of support for System.Drawing on Linux. Anyway, thanks.
