Use rust-analyzer in VSCode

We recommend you to use rust-analyzer extension in VSCode to support development of BlueOS kernel.

However, since we are using gn, rather than Cargo.toml, to manage our project, the rust-analyzer extension in VSCode might not work out-of-box. You should use following commands1 to get the extension work

gn gen out/qemu_mps2_an385 --export-rust-project
ln -sfn out/qemu_mps2_an385/rust-project.json
