Restore driver detection and X server configuration functionality

[ericbsd]

Restore comprehensive video driver detection and setup logic to xconfig, enabling automatic X11 configuration for diverse hardware platforms.

Driver Detection Improvements:

• Add NVIDIA GPU detection with version-specific driver selection

  • Latest driver (580) for RTX 40/50 series and Ada Generation cards
  • 470 driver for RTX 20/30 series and Pascal/Turing cards
  • 390 driver for GTX 600-900 series and Kepler/Maxwell cards
  • 340 driver for GTX 200-500 series and Tesla/Fermi cards
  • 304 driver for GeForce 6/7/8/9 series legacy cards

• Add AMD Radeon device ID database for radeonkms vs amdgpu selection

  • 400+ legacy Radeon device IDs requiring radeonkms driver
  • Automatic amdgpu selection for newer cards (Polaris+)

Configuration Management:

• Add comprehensive function documentation to all 50 functions

  • Hardware detection (GPU, VM platform, driver version)
  • Setup functions (DRM, legacy drivers, NVIDIA, virtualization)
  • Helper functions (rc.conf, package install, backup, logging)
  • Dialog/menu interface (bsddialog/dialog integration)
  • Entry points (cmd_auto, cmd_debug, interactive menu)

• Each function now includes:

  • Function name and description
  • Parameter specifications with explanations
  • Return value documentation
  • Practical usage examples

Platform Support:

• Intel GPU (DRM and legacy driver support)
• AMD GPU (automatic radeonkms/amdgpu selection)
• NVIDIA GPU (multi-version driver support)
• VirtualBox, VMware, QEMU, Hyper-V, bhyve VM guests
• Xorg and XLibre X server detection
• Offline package support (/xdrivers) with online fallback

This restores xconfig as a comprehensive tool for automatic X server configuration across GhostBSD's supported hardware platforms.
