KVM: SVM: Introduce hybrid-AVIC mode
Currently, AVIC is inhibited when booting a VM w/ x2APIC support.
because AVIC cannot virtualize x2APIC MSR register accesses.
However, the AVIC doorbell can be used to accelerate interrupt
injection into a running vCPU, while all guest accesses to x2APIC MSRs
will be intercepted and emulated by KVM.
With hybrid-AVIC support, the APICV_INHIBIT_REASON_X2APIC is
no longer enforced.
