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.
