johnzfitch a8ce084460 Fix NVIDIA environment variables for Maxwell/Pascal/Volta GPUs ...

Maxwell, Pascal, and Volta GPUs lack GSP (GPU System Processor) firmware
required by NVD_BACKEND=direct. Applying direct backend unconditionally
causes Aquamarine v3.3.0+ to fail with "Unknown-1" displays and blank screens.

Changes:
- Add GPU generation detection (Turing+ vs Maxwell/Pascal/Volta)
- Turing+ (RTX 20xx+, GTX 16xx): NVD_BACKEND=direct + LIBVA_DRIVER_NAME=nvidia
- Maxwell/Pascal/Volta: NVD_BACKEND=egl only (no GSP support)
- Both generations: __GLX_VENDOR_LIBRARY_NAME=nvidia (universal)

Regex improvements:
- Fix Turing+ detection (was using Maxwell/Pascal pattern)
- GT series: GT 1030 now properly detected (was missed)
- Quadro: P/M series only (exclude Kepler K-series)
- Volta: Titan V, Tesla V100, Quadro GV100
- Modern datacenter: A100, H100, T4, L-series
- MX series: Fixed to match MX150/250/450 (was only MX1-9)

Migration script (1770159912.sh) fixes existing broken installations by:
- Detecting legacy NVIDIA GPUs on existing systems
- Rewriting incompatible NVD_BACKEND=direct entries to egl
- Creating automatic backups before modification

Testing:
Validated against GT 1030, GTX 960/1080, Quadro P620 (legacy egl backend)
and GTX 1650, RTX 3080 (modern direct backend).

Preserves existing Turing+ behavior exactly. No impact on non-NVIDIA systems.
