fix: add a toggle to disable the dependency explorer

For common uses of non-Cargo build systems with rust-analyzer, the dependency view isn't particularly helpful because there isn't a Cargo.toml present for dependencies or the dependencies are part of the current workspace.

Speaking from the perspective of a user of `rust-project.json`, I'd prefer to have this feature disabled until I can add a field to `Crate` that defines the location of a build file (e.g., a `BUCK`) file, which would allow for removing the "search for a Cargo.toml in parent directories of a crate root" behavior that exists in a few places (I've opened [an issue](https://github.com/rust-lang/cargo/issues/12187) on Cargo to request this data from `cargo-metadata`).
