The new API call will be executing WFI and WFE instructions (Wait For Interrupt and Wait For Event, see https://developer.arm.com/documentation/100453/0401/Power-management/Wait-For-Interrupt-and-Wait-For-Event). These instructions are handled by KVM via kvm_handle_wfx().

@marpom so far this doesn't support all variants of WFx, and I couldn't trigger any exits with it. |

As Dmitry pointed out, we shouldn't be adding special instructions here, as we can use SYZOS_API_CODE instead |
