KVM: VMX: Move the shared "IRQs off" exit handler(s) to common code

Move vmx_handle_exit_irqoff() and its helpers to common.h / main.c to
capture that it's a common handler and to allow guarding against incorrectly
using to_vmx().

Opportunistically use a "vt" prefix instead of "vmx" to communicate that
it's a shared handler.

No functional change intended.
