scripts: generate_rust_analyzer.py: define scripts

Add IDE support for host-side scripts written in Rust. This support has
been missing since these scripts were initially added in commit
9a8ff24 ("scripts: add `generate_rust_target.rs`"), thus add it.

Change the existing instance of extension stripping to
`pathlib.Path.stem` to maintain code consistency.

Fixes: 9a8ff24 ("scripts: add `generate_rust_target.rs`")
