Currently accel_cpu_realize() only performs target-specific
realization. Introduce the cpu_common_[un]realize fields in
the base AccelClass to be able to perform target-agnostic
[un]realization of vCPUs.

accel_cpu_realize() is a generic function working with CPUs
from any target. Rename it using '_common_' to emphasis it is
not target specific.

We use the '*fn' suffix for handlers, this is a public method.
Drop the suffix.

Forward-declare AccelState in "qemu/typedefs.h" so structures
using a reference of it (like MachineState in "hw/boards.h")
don't have to include "qemu/accel.h".

The support of single-stepping is very much dependent on support from
the accelerator we are using. To avoid special casing in gdbstub move
the probing out to an AccelClass function so future accelerators can
put their code there.

We need to fetch the name of the current accelerator in flexible error
messages more going forward. Let's create a helper that gives it to us
without casting in the target code.

overall, all devices' realize functions take an Error **errp, but return void.
hw/core/qdev.c code, which realizes devices, therefore does:
local_err = NULL;
dc->realize(dev, &local_err);
if (local_err != NULL) {
goto fail;
}
However, we can improve at least accel_cpu to return a meaningful bool value.

avoid open coding the accesses to cpu->accel_cpu interfaces,
and instead introduce:
accel_cpu_instance_init,
accel_cpu_realizefn
to be used by the targets/ initfn code,
and by cpu_exec_realizefn respectively.

This will allow us to centralize the registration of
the cpus.c module accelerator operations (in accel/accel-softmmu.c),
and trigger it automatically using object hierarchy lookup from the
new accel_init_interfaces() initialization step, depending just on
which accelerators are available in the code.
Rename all tcg-cpus.c, kvm-cpus.c, etc to tcg-accel-ops.c,
kvm-accel-ops.c, etc, matching the object type names.
