XGA changes of the day (July 5th, 2025)

Browse Source 
1. Remove hackish ISA XGA add-on support (from now on, use the INMOS XGA card for ISA XGA support).
2. Correct timings when dispontime is on.
3. Add proper vga256 support on ISA XGA for NT 3.5x+ as well disable LFB support when asked (mainly when the aperture is on or when not extended mode) while keeping everything else happy.
