x86: Add Cooper Lake detection with AVX512BF16
All Sky Lake family processors have the same CPUID model number, 0x55.
The differences are Cascade Lake has AVX512VNNI and Cooper Lake has
AVX512VNNI + AVX512BF16. Check AVX512BF16 for Cooper Lake.
PR target/95774
* common/config/i386/cpuinfo.h (get_intel_cpu): Add Cooper Lake
detection with AVX512BF16.
