In the invocation of qdev_prop_set_chr(), "chardev" is the name of a
property rather than a type and has to match the name of the property
in device_class.rs. Do not use TYPE_CHARDEV here, just like in the C
version of pl011_create.

MaybeUninit::zeroed() is handy, but it introduces unsafe (and has a
pretty heavy syntax in general). Introduce a trait that provides the
same functionality while staying within safe Rust.
In addition, MaybeUninit::zeroed() is not available as a "const"
function until Rust 1.75.0, so this also prepares for having handwritten
implementations of the trait until we can assume that version.

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.

Right now the Rust pl011 device is included in all QEMU system
emulator binaries if --enable-rust is passed. This is not needed
since the board logic in hw/arm/Kconfig will pick it.

This commit adds a re-implementation of hw/char/pl011.c in Rust.
How to build:
1. Configure a QEMU build with:
--enable-system --target-list=aarch64-softmmu --enable-rust
2. Launching a VM with qemu-system-aarch64 should use the Rust version
of the pl011 device

Patch was applied with invalid authorship by accident, which confuses
git tooling that look at git blame for contributors etc.
Patch will be re-applied with correct authorship right after this
commit.
This reverts commit d0f0cd5b1f.
