feat(fws_windows): add intel vmd device detection and support

Add support for detecting Intel VMD (Volume Management Device) controllers and enable/disable the VMD checkbox based on detection.

Changes:
- Add _intel_vmd_present() function to detect VMD controllers via lspci
- Initialize _vmd attribute based on controller detection
- Add VMD checkbox widget binding and state management
- Update checkbox sensitivity when enabling/disabling dual-boot
- Persist VMD state in configuration file
- Load VMD state from saved configuration
