rust: add PL011 device model

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 Co-authored-by: Junjie Mao <junjie.mao@intel.com> Co-authored-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Junjie Mao <junjie.mao@intel.com> Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Link: https://lore.kernel.org/r/20241024-rust-round-2-v1-2-051e7a25b978@linaro.org
