Add Windows 11 VM configuration and setup for GPU passthrough

- Created a new XML configuration file for Windows 11 VM with enhanced resource allocation and device settings.
- Added an old configuration file for reference.
- Implemented an Ansible playbook to set up a GPU passthrough host on Fedora, including necessary package installations, GRUB configuration, and udev rules for persistent device access.
- Introduced a Python script to monitor CPU power usage via Intel RAPL interface.
