AVX10_XMM, AVX10_YMM and AVX10_ZMM feature bits were from the earlier
version of AVX10 specification.  Intel AVX10 specification published in
June 2026:

https://www.intel.com/content/www/us/en/developer/articles/technical/intel-s
dm.html

support both AVX2 and AVX512.  These bits are reserved now and should
be 1.  Set AVX10 active only if XMM/YMM/ZMM are supported and set
AVX10_VERSION active only if AVX10 is active.

This fixes BZ #34554.
