rust-project: Represent source roots properly

The current structure of a rust-project.json is documented here:
https://rust-analyzer.github.io/manual.html#non-cargo-based-projects

There are a couple of differences from what gn previously generated:
* There is no longer a 'roots' section
* Each crate has its own set of source includes and exclude directories.

This difference has prevented rust-analyzer from correctly spotting and
including Rust files pulled into a crate using the include! macro. With
the current change, 'gen' dirs are included such that such generated
files can be identified and correctly included by rust-analyzer.
