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.

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.

Refine the documentation to clarify:
* `unsfae` requires that `VALUE` must be valid.
* using `*const` instead of `&` because the latter will cause compiler
error.

We want a &raw pointer, so unsafe { &_ } is not needed.
