x86: vmx: Add test for L2 change of CR4.OSXSAVE

If L1 allows L2 to modify CR4.OSXSAVE, then L0 kvm recalculates the
guest's CPUID.01H:ECX.OSXSAVE bit when the L2 guest changes
CR4.OSXSAVE via MOV-to-CR4. Verify that kvm also recalculates this
CPUID bit when loading L1's CR4 from the "host CR4" field of the
VMCS12.
