Setup editor file associations for non-rs extensions

.gitattributes lists *.fixed, *.pp, and *.mir as file extensions which
should be treated as Rust source code. Do the same for VS Code and Zed.
This only does syntax highlighting, which is appropriate, as MIR isn't
really Rust code.

At the same time, consistently order `rust-analyzer.linkedProjects`
between editors. For some reason, Eglot didn't include
library/Cargo.toml.
