Rust Cargo linter: Improve workspace support (#1679)

* Rust Cargo linter: Improve workspace support

When using Cargo workspaces [1], there is a 'Cargo.toml' directory in a
top level directory, listing all the crates in the project. If we are
currently editing one of the crates, 'cargo build' should execute in
that directory for that crate's separate `Cargo.toml`, otherwise Cargo
may spend more time possibly rebuilding the entire workspace, and maybe
failing on one of the other crates, instead of succeeding on the current.

When defined, ALE will set the `--features` option when invoking `cargo` to
perform the lint check. See |g:ale_rust_cargo_default_feature_behavior|.

Type: |Number|
Default: `1`
When set to 1, and ALE is used to edit a crate that is part of a Cargo
workspace, avoid building the entire entire workspace by invoking
`cargo` directly in the crate's directory. Otherwise, behave as usual.
