Oliver Anderson 193e99c23a arch: Add compatibility check for CPUID.0x7.0x1:EDX
Register EDX of CPUID leaf 0x7 sub-leaf 0x1 (Structured Extended Feature
Enumeration Sub-leaf) is currently not checked, but it should be.

KVM supports several of the features enumerated by this value when they
are supported by the host, such as AVX-VNNI-INT8, AMX-COMPLEX, AVX10
and more.

The migration destination needs to support any such feature exposed to
the guest from the migration source.
