Leander Kohler c698075157 vmm: add guest exit event path ...

Introduce a dedicated guest_exit_evt and a matching epoll dispatch
path for guest-triggered shutdowns.

This series is needed because managment software such as libvirt may
still need the Cloud Hypervisor process to stay alive after the guest
has shut down.
Today a guest-triggered shutdown can make the VMM disappear immediately,
which means the managment software can lose track of the VM run-state.

This must only apply to guest-triggered shutdowns. Fatal error paths
and other internal exit paths must keep using the existing VMM exit
handling.

For now GuestExit still calls vmm_shutdown(), so this commit only adds
the separate plumbing and keeps the current behavior unchanged.
