KVM: VMX: Move the shared NMI handler/trampoline to common code

Move vmx_handle_nmi() to 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, and move the declaration higher up in common.h so
that it doesn't get buried in a pile of inline helpers (more are on the
way).

No functional change intended.
