VMM AMD AVIC work. Currently SMP Ubuntu 26.04 boots fine with up to 4 VCPUs. There's still work to be done but this is a good point to commit upstream.

Fixed a typo (% vs &) in hmR0SvmExitAvicNoAccel.
Ubuntu 26 VM single-VCPU now boots fully without manually triggering an
interrupt, like for example pressing a key.
… interrupt from the APIC when AMD AVIC is enabled.

This fixes the SMP issue while booting Ubuntu 26 VMs with AVIC.
