[PATCH v4 3/6] KVM: x86: Move "emulate hypercall" function declarations to x86.h

[Sean Christopherson <seanjc@google.com>]

Move the declarations for the hypercall emulation APIs to x86.h.  While
the helpers are exported, they are intended to be consumed only KVM vendor
modules, i.e. don't need to exposed to the kernel at-large.

No functional change intended.
