Zide Chen 6d7eb6d7b6 hv: emulate IA32_EFER and adjust Load EFER VMX controls ...

This helps to improve performance:

- Don't need to execute VMREAD in vcpu_get_efer(), which is frequently
  called.

- VMX_EXIT_CTLS_SAVE_EFER can be removed from VM-Exit Controls.

- If the value of IA32_EFER MSR is identical between the host and guest
  (highly likely), adjust the VMX controls not to load IA32_EFER on
  VMExit and VMEntry.

It's convenient to continue use the exiting vcpu_s/get_efer() APIs,
other than the common vcpu_s/get_guest_msr().
