S3 and Cirrus updates of the first day of winter (December 21, 2024)

Browse Source 
Cirrus 5436/46 and 5480.
Finally fixed the Solaris 2.6 font issue, was a dword swap one with color expansion.

S3.
1. Make 868/968 ignore horizontal skew, ergo horizontal override until a proper solution is found regarding hardware tests.
2. Fixed a minor mix issue with S3 911/924 Win3.1 drivers in 8bpp mode.
