Updated rust-analyzer to use repo vs generated files as crate roots (#2717)

This change updates the `rust_analyzer_aspect` to attempt to match
generated crate root sources to `srcs` inputs and use the the path of
the source file in place of the generated path. The generated path is
then added to `sources.include_dirs` for compatibility. The impact of
this can be seen in the following diff of the
`@rules_rust//:rust-project.json` file:
