Zhao Liu 0a7fe8d407 rust/qdev: Drop declare_properties & define_property macros 
After HPET's #property conversion, there's no use case for
declare_properties & define_property. So get rid of them for now.

In future, if there's something that #property really cannot resolve,
they can be brought back.

Zhao Liu b160ebadc1 rust/hpet: Convert qdev properties to #property macro 
Convert HPET's properties to #property macro:
 * num_timers: usize property.
 * flags: u32 bit property.
 * int_route_cap: u32 property.
 * hpet_offset_saved: bool property.

Zhao Liu 4f09cf54fa rust/hpet: Clean up type mismatch for num_timers property 
Now `num_timers` is `usize` other than `u8`. Although the type field in
`declare_properties` macro hasn't been used, it's better to explicitly
point this out and clean up this before doing other property work.

Zhao Liu a8f080215f rust/qdev: Test bit property for #property 
There's a diference between Rust and C:

Though C macro (e.g., DEFINE_PROP_BIT or DEFINE_PROP_BIT64) always
requires default value, Rust side allows to omit this "default" field
in #property, and provides a default value ("0" - false) for this
field.

This minor difference does not break user habits and should be
acceptable. Therefore, the test cases also cover this scenario.

Zhao Liu 9686aa9a05 rust/qdev: Support bit property in #property macro 
Add BIT_INFO to QDevProp trait, so that bit related property info could
be bound to u32 & u64.

Then add "bit=*" field in #property attributes macro to allow device to
configure bit property.

In addtion, convert the #property field parsing from `if-else` pattern
to `match` pattern, to help readability. And note, the `bitnr` member of
`Property` struct is generated by manual TokenStream construction,
instead of conditional repetition (like #(bitnr: #bitnr,)?) since
`quote` doesn't support this.

In addtion, rename VALUE member of QDevProp trait to BASE_INFO.

And update the test cases about qdev property.

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.

Zhao Liu 7da9ee9207 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.

Manos Pitsidianakis a71df7e143 rust: add qdev Device derive macro 
Add derive macro for declaring qdev properties directly above the field
definitions. To do this, we split DeviceImpl::properties method on a
separate trait so we can implement only that part in the derive macro
expansion (we cannot partially implement the DeviceImpl trait).

Adding a `property` attribute above the field declaration will generate
a `qemu_api::bindings::Property` array member in the device's property
list.

As more crates start using the same dependencies, it's better to not

Manos Pitsidianakis 4344b358a8 rust: declare self as qemu_api for proc-macros 
Fix an outstanding TODO.

Declaring `extern crate self as qemu_api` allows use of `qemu_api`
within the qemu_api crate; this allows the Wrapper derive macro and
future proc macros to be used interchangeably in the qemu_api crate and
other crates. This is not required currently and is only for
future-proofing.
