ef130a3bf9 sel4/x86: implement vm_session interface
Issue #3111

- enable vt-x in kernel configuration

Kernel patches:

- add unrestricted guest support
- avoid kernel boot failure when vt-x is not available
- avoid nullpointer in kernel when vcpu is not fully setup
- avoid vcpu scheduling bug which causes starvation on same/below prio level
- save efer register correctly from guest
