hyperv: split hyperv-proto.h into x86 and arch-independent parts 



Some parts of the Hyper-V hypervisor-guest interface appear to be
target-independent, so move them into a proper header.

Not that Hyper-V ARM64 emulation is around the corner but it seems more
conveninent to have most of Hyper-V and VMBus target-independent, and
allows to avoid conflicts with inclusion of arch-specific headers down
the road in VMBus implementation.
