tidy: Add a check to ensure Cargo.toml is in sync

This verifies that the crates listed in the `[dependencies]` section of
`Cargo.toml` are a subset of the crates listed in `lib.rs` for our in-tree
crates. This should help ensure that when we refactor crates over time we keep
these dependency lists in sync.
