x86: Add support for AVX10 preset and vec size in cpu-features
This commit add support for the new AVX10 cpu features:
https://cdrdv2-public.intel.com/784267/355989-intel-avx10-spec.pdf
We add checks for:
- `AVX10`: Check if AVX10 is present.
- `AVX10_{X,Y,Z}MM`: Check if a given vec class has AVX10 support.
`make check` passes and cpuid output was checked against GNR/DMR on an
emulator.
