accel: Add xen CpusAccel using dummy-cpus
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.
