rust/vmstate: Add support for field_exists checks

Unfortunately, at present it's not possible to have a const
"with_exist_check" method to append test_fn after vmstate_struct (due
to error on "constant functions cannot evaluate destructors" for `F`).

Before the vmstate builder, the only way to support "test_fn" is to
extend vmstate_struct macro to add the such new optional member (and
fortunately, Rust can still parse the current expansion!).

Abstract the previous callback implementation of vmstate_validate into
a separate macro, and moves it before vmstate_struct for vmstate_struct
to call.

Note that there's no need to add any extra flag for a new test_fn added
in the VMStateField.

rust/vmstate: Support vmstate_validate

In C version, VMSTATE_VALIDATE accepts the function pointer, which is
used to check if some conditions of structure could meet, although the
C version macro doesn't accept any structure as the opaque type.

But it's hard to integrate VMSTATE_VALIDAE into vmstate_struct, a new
macro has to be introduced to specifically handle the case corresponding
to VMSTATE_VALIDATE.

One of the difficulties is inferring the type of a callback by its name
`test_fn`. We can't directly use `test_fn` as a parameter of
test_cb_builder__() to get its type "F", because in this way, Rust
compiler will be too conservative on drop check and complain "the
destructor for this type cannot be evaluated in constant functions".

Fortunately, PhantomData<T> could help in this case, because it is
considered to never have a destructor, no matter its field type [*].

The `phantom__()` in the `call_func_with_field` macro provides a good
example of using PhantomData to infer type. So copy this idea and apply
it to the `vmstate_validate` macro.

rust/vmstate: Re-implement VMState trait for timer binding

At present, Rust side has a timer binding "timer::Timer", so the vmstate
for timer should base on that binding instead of the raw
"binding::QEMUTimer".

It's possible to apply impl_vmstate_transparent for cell::Opaque and
then impl_vmstate_forward for timer::Timer. But binding::QEMUTimer
shouldn't be used directly, so that vmstate for such raw timer type is
useless.

Thus, apply impl_vmstate_scalar for timer::Timer. And since Opaque<> is
useful, apply impl_vmstate_transparent for cell::Opaque as well.

rust/vmstate: Relax array check when build varray in vmstate_struct

The varry of structure created by vmstate_struct is different with
vmstate_of. This is because vmstate_struct uses the `vmsd` to traverse
the vmstates of structure's fields, rather than treating the structure
directly as a well-defined vmstate.

Therefore, there's no need to check array flag when building varray by
vmstate_struct.

rust/vmstate: Fix unnecessary VMState bound of with_varray_flag()

The VMState type bound is not used in with_varray_flag().

And for vmstate_struct, Rust cannot infer the type of `num` from the
call_func_with_field(), so this causes the compiling error because it
complains "cannot satisfy `_: VMState`" in with_varray_flag().

Note Rust can infer the type in vmstate_of macro so that
with_varray_flag() can work at there. It is possible that the different
initialization ways in the two macros cause differences in Rust's
type inference.

But in fact, the VMState type bound is not used in with_varray_flag()
and vmstate_varray_flag() has already checked the VMState type, it's
safe to drop VMState bound of with_varray_flag(), which can fix the
above compiling error.

rust/vmstate: Fix type check for varray in vmstate_struct

When pass a varray to vmstate_struct, the `type` parameter should be the
type of the element in the varray, for example:

vmstate_struct!(HPETState, timers, [0 .. num_timers], VMSTATE_HPET_TIMER,
BqlRefCell<HPETTimer>).with_version_id(0)

But this breaks current type check, because it checks the type of
`field`, which is an array type (for the above example, type of timers
is [BqlRefCell<HPETTimer>; 32], not BqlRefCell<HPETTimer>).

But the current assert_field_type() can no longer be extended to include
new arguments, so a variant of it (a second macro containing the
`num = $num:ident` parameter) had to be added to handle array cases.

In this new macro, it not only checks the type of element, but also
checks whether the `num` (number of elements in varray) is out of range.
