Xen was broken by commit 1583a3898853 ("cpus: extract out qtest-specific
code to accel/qtest"). Xen relied on qemu_init_vcpu() calling
qemu_dummy_start_vcpu() in the default case, but that was replaced by
g_assert_not_reached().
Add a minimal "CpusAccel" for Xen using the dummy-cpus implementation
used by qtest.

CONFIG_XEN is generated by configure and stored in "config-target.h",
which is (obviously) only include for target-specific objects.
This is a problem for target-agnostic objects as CONFIG_XEN is never
defined and xen_enabled() is always inlined as 'false'.
Fix by following the KVM schema, defining CONFIG_XEN_IS_POSSIBLE
when we don't know to force the call of the non-inlined function,
returning the xen_allowed boolean.
Fixes: da278d58a092 ("accel: Move Xen accelerator code under accel/xen/")

Xen PCI passthrough support may not be available and thus the global
variable "has_igd_gfx_passthru" might be compiled out. Common code
should not access it in that case.
Unfortunately, we can't use CONFIG_XEN_PCI_PASSTHROUGH directly in
xen-common.c so this patch instead move access to the
has_igd_gfx_passthru variable via function and those functions are
also implemented as stubs. The stubs will be used when QEMU is built
without passthrough support.
Now, when one will want to enable igd-passthru via the -machine
property, they will get an error message if QEMU is built without
passthrough support.
Fixes: 46472d82322d0 ('xen: convert "-machine igd-passthru" to an accelerator property')

This code is not related to hardware emulation.
Move it under accel/ with the other hypervisors.
