libvmmapi: Conditionalize compilation of some functions

Hide definitions of several functions that currently don't have
implementatations in the arm64 vmm port. In particular, add a
WITH_VMMAPI_SNAPSHOT preprocessor variable that can be used to enable
compilation of save/restore functions, and conditionalize compilation of
some functions only used by amd64 bhyve. If in the long term they
remain amd64-only, they can move to vmmapi_machdep.c, but for now it's
not clear to me that that's the right thing to do.

libvmmapi: Make vm_raise_msi() a common function

Currently, bhyve PCI emulation uses vm_lapic_msi() to raise an MSI in
the guest. The arm64 port has a similar function, vm_raise_msi().
Add vm_raise_msi() on amd64 as well and have it simply call
vm_lapic_msi() so that bhyve can use a common, generically named
function.

libvmmapi: Move PCI passthrough ioctl wrappers into a separate file

The arm64 port doesn't implement PCI passthrough and in particular
doesn't define the ioctls used by these wrappers. It might be that the
ppt ioctl interface will require modification to support arm64. Until
that's sorted out one way or another, put this code in a separate file
so that it's easy to conditionally compile.

No functional change intended.

libvmmapi: Split the ioctl list into MI and MD lists

To enable use in capability mode, libvmmapi needs a list of all the
ioctls that might be invoked on the vmm device handle. Some of these
ioctls are amd64-specific. Move the ioctl list to vmmapi_machdep.c and
define a list of MI ioctls so that the arm64 port can build its own list
without duplicating common ioctls. No functional change intended.

libvmmapi: Move some ioctl wrappers to vmmapi_machdep.c

ioctls relating to segments and various x86-specific interrupt
controllers are easy candidates to move to vmmapi_machdep.c.

In vmmapi.h I'm just ifdefing MD prototypes for now. We could instead
split vmmapi.h into multiple headers, e.g., vmmapi.h and
vmmapi_machdep.h, but it's not obvious to me yet that that's the right
approach.
