This allows a cpu to enter idle state after hanlding an interrupt, while leaving the interrupt in the correct state. If this was not carried out, the cpu might not wake up on another interrupt because it is still handling the current interrupt or the same interrupt might not be triggered again.

This PR adds support for VM reset. Guest can request a VM reset by issuing standard system calls, i.e., PSCI_RESET and SBI_SRST, for arm and risc-v systems, respectively.
It starts by adding support for allowing CPUs to go idle in the middle of an interrupt. This is necessary because CPUs will receive an IPI from the CPU that emitted the reset and will be required to go idle if they are not the VM's primary CPU.
Besides the generic VM rest logic and the arch-specific calls for requesting a reset, this PR adds arch-specific logic to reset the virtual interrupt controllers.
