target/i386: Added VGIF feature
VGIF allows STGI and CLGI to execute in guest mode and control virtual
interrupts in guest mode.
When the VGIF feature is enabled then:
* executing STGI in the guest sets bit 9 of the VMCB offset 60h.
* executing CLGI in the guest clears bit 9 of the VMCB offset 60h.
