  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_V{1..255}`: Check if a given version is active.
    - `AVX10_{X,Y,Z}MM`: Check if a given vec class has AVX10 support.

The version checks are not ideal, the reason for the reason for this
is the version information in AVX10 is encoded as complete a byte
value, but the `CPU_FEATURES` interface is only able to query bools.

To get around this, we add a feature for each possible version value
(starting at 1 as there is no AVX10 version 0).

`make check` passes and cpuid output was checked against GNR/DMR on an
emulator.
