Video changes of the day (January 26th, 2025)

XGA:
1. Added a proper poll so to have its timings independent of the SVGA core and changes its renderer accordingly, mainly a blank render one.
2. Workaround the Ctrl-Alt-Del reset of Windows 2.x so that it switches back to VGA text mode correctly when using the 0xA000 64K aperture (in vid_svga.c).

SVGA core:
Re-organized the way the different timers are organized so that the XGA and 8514/A pollers can coexist with the SVGA timer without conflicts.

ATI Mach32:
Reworked the true color renderer and made it a Mach32 exclusive due to its differences from the standard one. Fixes wrong rendered colors in NT using the 32bpp renderer in RGB mode.
