rust: pl011: Really use RX FIFO depth
While we model a 16-elements RX FIFO since the PL011 model was introduced in commit cdbdb648b7c ("ARM Versatile Platform Baseboard emulation"), we only read 1 char at a time!
Have can_receive() return how many elements are available, and use that in receive().
This is the Rust version of commit 3e0f118f825 ("hw/char/pl011: Really use RX FIFO depth"); but it also adds back a comment that is present in commit f576e0733cc ("hw/char/pl011: Add support for loopback") and absent in the Rust code.

rust: pl011: Check size of state struct at compile time
The PL011 device's C implementation exposes its PL011State struct to users of the device, and one common usage pattern is to embed that struct into the user's own state struct. (The internals of the struct are technically visible to the C user of the device, but in practice are treated as implementation details.)
This means that the Rust version of the state struct must not be larger than the C version's struct; otherwise it will trip a runtime assertion in object_initialize_type() when the C user attempts to in-place initialize the type.
Add a compile-time assertion on the Rust side, so that if we accidentally make the Rust device state larger we know immediately that we need to expand the padding in the C version of the struct.

rust: pl011: Allow NULL chardev argument to pl011_create()
It's valid for the caller to pass a NULL chardev to pl011_create(); this means "don't set the chardev property on the device", which in turn means "act like there's no chardev". All the chardev frontend APIs (in C, at least) accept a NULL pointer to mean "do nothing".
This fixes some failures in 'make check-functional' when Rust support is enabled.

rust: pl011: pass around registers::Data
The values stored in the Fifo are instances of the bitfield-struct registers::Data. Convert as soon as possible the value written into DR, and always refer to the bitfield struct; it's generally cleaner other than PL011State::receive having to do a double conversion u8=>u32=>registers::Data.

rust: pl011, qemu_api tests: do not use ClassInitImpl
Outside the qemu_api crate, orphan rules make the usage of ClassInitImpl unwieldy. Now that it is optional, do not use it.
For PL011Class, this makes it easier to provide a PL011Impl trait similar to the ones in the qemu_api crate. The device id consts are moved there.

rust: qom: add ObjectImpl::CLASS_INIT
As shown in the PL011 device, the orphan rules required a manual implementation of ClassInitImpl for anything not in the qemu_api crate; this gets in the way of moving system emulation-specific code (including DeviceClass, which as a blanket ClassInitImpl<DeviceClass> implementation) into its own crate.
Make ClassInitImpl optional, at the cost of having to specify the CLASS_INIT member by hand in every implementation of ObjectImpl. The next commits will get rid of it, replacing all the "impl<T> ClassInitImpl<Class> for T" blocks with a generic class_init<T> method on Class.
Right now the definition is always the same, but do not provide a default as that will not be true once ClassInitImpl goes away.
