60f8ab2a36 add preliminary AVX10.1 handling 
AVX10.1 includes the following AVX extensions:
	x86_feature(BX_ISA_AVX512, "avx512")                                    /* AVX-512 instruction */
	x86_feature(BX_ISA_AVX512_DQ, "avx512dq")                               /* AVX-512DQ instruction */
	x86_feature(BX_ISA_AVX512_BW, "avx512bw")                               /* AVX-512 Byte/Word instruction */
	x86_feature(BX_ISA_AVX512_CD, "avx512cd")                               /* AVX-512 Conflict Detection instruction */
	x86_feature(BX_ISA_AVX512_VBMI, "avx512vbmi")                           /* AVX-512 VBMI : Vector Bit Manipulation Instructions */
	x86_feature(BX_ISA_AVX512_VBMI2, "avx512vbmi2")                         /* AVX-512 VBMI2 : Vector Bit Manipulation Instructions */
	x86_feature(BX_ISA_AVX512_IFMA52, "avx512ifma52")                       /* AVX-512 IFMA52 Instructions */
	x86_feature(BX_ISA_AVX512_VPOPCNTDQ, "avx512vpopcnt")                   /* AVX-512 VPOPCNTD/VPOPCNTQ Instructions */
	x86_feature(BX_ISA_AVX512_VNNI, "avx512vnni")                           /* AVX-512 VNNI Instructions */
	x86_feature(BX_ISA_AVX512_BITALG, "avx512bitalg")                       /* AVX-512 BITALG Instructions */
	x86_feature(BX_ISA_AVX512_BF16, "avx512bf16")                           /* AVX-512 BF16 Instructions */
	x86_feature(BX_ISA_AVX512_FP16, "avx512fp16")                           /* AVX-512 FP16 Instructions */

And it could be handling 256-bit only, in this case avx10_1 will be enabled but avx10_vl512 will not.
Bochs will support all relevant instructions but without 512 bit mode in this case, attemp to encode VL512 in EVEX will result in #UD
also added support for AVX10 CPUID leaf 0x24

60491a64cf Cirrus: Added horizontal pixel panning support for 8, 15 and 16 bpp modes. 
Original Cirrus VGABIOS uses this feature in VBE function 0x07 since the
screen start address is dword aligned. It's only documented for standard VGA,
but not for the extended Cirrus modes.
TODO: Implement this in the LGPL'd VGABIOS.
