rust: modernize link_section usage for ELF platforms
Some newer ABI implementations do not provide .ctors; and while
some linkers rewrite .ctors into .init_array, not all of them do.
Use the newer .init_array ABI, which works more reliably, and
apply it to all non-Apple, non-Windows platforms.
This is similar to how the ctor crate operates; without this change,
"#[derive(Object)]" does not work on Fedora 41.

rust: remove uses of #[no_mangle]
Mangled symbols do not cause any issue; disabling mangling is only useful if
C headers reference the Rust function, which is not the case here.

rust: do not use --no-size_t-is-usize
This is not necessary and makes it harder to write code that is
portable between 32- and 64-bit systems: it adds extra casts even
though size_of, align_of or offset_of already return the right type.

rust: add utility procedural macro crate
This commit adds a helper crate library, qemu-api-macros for derive (and
other procedural) macros to be used along qemu-api.
It needs to be a separate library because in Rust, procedural macros, or
macros that can generate arbitrary code, need to be special separate
compilation units.
Only one macro is introduced in this patch, #[derive(Object)]. It
generates a constructor to register a QOM TypeInfo on init and it must
be used on types that implement qemu_api::definitions::ObjectImpl trait.
