Implement virtual timer for secondary VMs. If the timer fires while the secondary VM is running, the physical interrupt will go to the primary VM, which should then run the secondary again. Hafnium will then inject the virtual timer interrupt automatically, and mask the timer interrupt so it doesn't immediately go back to the primary. Note that the secondary must clear this mask before it can get another timer interrupt. Bug: 117271574 Change-Id: If90a3c4fd133333713ad6bf7d6a3b515ae6fea6a
