rust/pl011: Fix range checks for device ID accesses

The peripheral and PrimeCell identification registers of pl011 are located at
offset 0xFE0 - 0xFFC. To check if a read falls to such registers, the C
implementation checks if the offset-shifted-by-2 (not the offset itself) is in
the range 0x3F8 - 0x3FF.

Use the same check in the Rust implementation.

This fixes the timeout of the following avocado tests:

* tests/avocado/boot_linux_console.py:BootLinuxConsole.test_arm_virt
* tests/avocado/replay_kernel.py:ReplayKernelNormal.test_arm_virt
* tests/avocado/replay_kernel.py:ReplayKernelNormal.test_arm_vexpressa9

rust: introduce alternative implementation of offset_of!

offset_of! was stabilized in Rust 1.77.0. Use an alternative implemenation
that was found on the Rust forums, and whose author agreed to license as
MIT for use in QEMU.

The alternative allows only one level of field access, but apart
from this can be used just by replacing core::mem::offset_of! with
qemu_api::offset_of!.

The actual implementation of offset_of! is done in a declarative macro,
but for simplicity and to avoid introducing an extra level of indentation,
the trigger is a procedural macro #[derive(offsets)].

The procedural macro is perhaps a bit overengineered, but it helps
introducing some idioms that will be useful in the future as well.

rust: use std::os::raw instead of core::ffi

core::ffi::c_* types were introduced in Rust 1.64.0. Use the older types
