!113 SPR: KVM: Add SPR new instructions for virtualization

Merge Pull Request from: @allen-shi 
 
This PR is to add KVM support for SPR new instructions, which include AVX_VNNI and AVX512_FP16 new instructions.

Intel-Kernel Issue
[#I5O6WB](https://gitee.com/openeuler/intel-kernel/issues/I5O6WB)

Test
Boot host with kernel that having KVM support for SPR new instructions and launch a guest VM with kernel that also have the support for SPR new instructions.

Then in the guest VM, we can find "avx_vnni" and "avx512_fp16" in /proc/cpuinfo.

Known Issue
N/A
