Add `Config::hash_untracked_state` callback For context, I'm looking to use [late module passes](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_lint/context/struct.LintStore.html#structfield.late_module_passes) in Clippy which unlike regular late passes run incrementally per module However we have a config file which can change between runs, we need changes to that to invalidate the `lint_mod` query. This PR adds a side channel for us to hash some extra state into `Options` in order to do that This does not make any changes to Clippy, I plan to do that in a PR to the Clippy repo along with some other required changes An alternative implementation would be to add a new query to track this state and override the `lint_mod` query in Clippy to first call that cc `@rust-lang/clippy` |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
