VM creation through libvirt domain xml format

This merge request implements VM creation using the libvirt domain XML format and removes virt-install as a dependency, addressing some of issue #5 (closed) as well as a few other things listed below.

Summary of changes:

• general domain properties of domain.cpp extracted to domainconfig.cpp
• more domain config properties are stored and can be parsed from xml file
• installer feature - attempts to identify the os of user given disk image using libosinfo, otherwise prompts user to provide an os short-id
• uses libosinfo to get data of os properties (architecture, id, ...) for the xml file
• uses qdomdocument to generate a basic domain XML file (QEMU/KVM only),
• does not use CLI of virt-install anymore. see domaininstaller::generateXML() for xml elements supported
• uses qemu-img CLI to generate a virtual disk of specified size
• exposes objects to qml through qmlmodules (changes to cmake)

NOTE: certain devices configuration are minimal and also things are hardcoded to only work with QEMU/KVM. I have tested with making vms of fedora40, win10, and ubuntu22.04, and a few others.

Stores files in:

• xml path: /home/{username}/.local/share/libvirt/kde-karton/config

• virtual disk path: /home/{username}/.local/share/libvirt/images

Example: a config created by karton

New dependencies: libosinfo-1.0, glib

TODO:

• finish extracting domain configuration from domain.cpp to new class
• finish hardcode of all elements of domain xml
• parameterize device, architecture, os id etc elements using libosinfo
• redo config object
• refreshing libvirt vms by parsing xml files for some info rather than getting from libvirt api

Later:

• properly use and store libvirt objects of network and storage pools
• support for controller devices
• extract and group domain configuration classes more
• rework ui, add properties tabs to have room for newer domain properties
• test and ensure compatibility with GNOME Boxes
