All interrupts and exceptions pass a struct cpu_user_regs up into C. This
contains the legacy vm86 fields from 32bit days, which are beyond the
hardware-pushed frame.
Accessing these fields is generally illegal, as they are logically out of
bounds for anything other than an interrupt/exception hi

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-cpu implementation
Xen was left behind when CpusAccel became mandatory and fails the assert
in qemu_init_vcpu(). It relied on the same dummy cpu threads as qtest.
Move the qtest cpu functions to a common location and reuse them for
Xen.
