Now that const_refs_static can be assumed, convert the members of
the DeviceImpl trait from functions to constants. This lets the
compiler know that they have a 'static lifetime, and removes the
need for the weird "Box::leak()".

rust: vmstate: use const_refs_to_static
The VMStateDescriptionBuilder already needs const_refs_static, so
use it to remove the need for vmstate_clock! and vmstate_struct!,
as well as to simplify the implementation for scalars.
If the consts in the VMState trait can reference to static
VMStateDescription, scalars do not need the info_enum_to_ref!
indirection and structs can implement the VMState trait themselves.

rust: vmstate: convert to use builder pattern
Similar to MemoryRegionOps, the builder pattern has two advantages:
1) it makes it possible to build a VMStateDescription that knows which
types it will be invoked on; 2) it provides a way to wrap the callbacks
and let devices avoid "unsafe".
Unfortunately, building a static VMStateDescription requires the
builder methods to be "const", and because the VMStateFields are
*also* static, this requires const_refs_static. So this requires
Rust 1.83.0.

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: 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.
