rust: qom: change instance_init to take a ParentInit<>

This removes undefined behavior associated to writing to uninitialized
fields, and makes it possible to remove "unsafe" from the instance_init
implementation.

However, the init function itself is still unsafe, because it must promise
(as a sort as MaybeUninit::assume_init) that all fields have been
initialized.

rust: hpet: fully initialize object during instance_init

The array of BqlRefCell<HPETTimer> is not initialized yet at the
end of instance_init. In particular, the "state" field is NonNull
and therefore it is invalid to have it as zero bytes.

Note that MaybeUninit is necessary because assigning to self.timers[index]
would trigger Drop of the old value.

rust/hpet: Drop BqlCell wrapper for num_timers

Now that the num_timers field is initialized as a property, someone may
change its default value using qdev_prop_set_uint8(), but the value is
fixed after the Rust code sees it first. Since there is no need to modify
it after realize(), it is not to be necessary to have a BqlCell wrapper.

rust/hpet: change type of num_timers to usize

Remove the need to convert after every read of the BqlCell. Because the
vmstate uses a u8 as the size of the VARRAY, this requires switching
the VARRAY to use num_timers_save; which in turn requires ensuring that
the num_timers_save is always there. For simplicity do this by
removing support for version 1, which QEMU has not been producing for
~15 years.
