Both insert/remove_breakpoint() handlers are used in system and
user emulation. We can not use the 'hwaddr' type on user emulation,
we have to use 'vaddr' which is defined as "wide enough to contain
any #target_ulong virtual address".
gdbstub.c doesn't require to include "exec/hwaddr.h" anymore.

This removes the final hard coding of kvm_enabled() in gdbstub and
moves the check to an AccelOps.

As HW virtualization requires specific support to handle breakpoints
lets push out special casing out of the core gdbstub code and into
AccelOpsClass. This will make it easier to add other accelerator
support and reduces some of the stub shenanigans.

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.

Clean up the error handling in kvm_init_vcpu so we can see what went
wrong more easily.
Make it take an Error ** and fill it out with what failed, including
the cpu id, so you can tell if it only fails at a given ID.
Replace the remaining DPRINTF by a trace.
This turns a:
kvm_init_vcpu failed: Invalid argument
into:
kvm_init_vcpu: kvm_get_vcpu failed (256): Invalid argument
and with the trace you then get to see:
19049@1595520414.310107:kvm_init_vcpu index: 169 id: 212
19050@1595520414.310635:kvm_init_vcpu index: 170 id: 256
qemu-system-x86_64: kvm_init_vcpu: kvm_get_vcpu failed (256): Invalid argument
which makes stuff a lot more obvious.
