Auto merge of #13088 - Jarcho:conf_refactor2, r=flip1995

Create lint passes using `Conf`

This slightly reduces the amount of code changes needed to add a config to a lint and makes things makes things more consistent between passes. A dependence on the config being a static reference is also added. This would only ever be a problem if multiple crates end up compiled in a single process.

Other changes include:
* Removing useless `#[derive(..)]`s
* Removing `#[must_use]` on lint pass constructors.
* Unified the parsing of the `DisallowedPath` struct in lint passes.
* Update `disallowed_types` and `await_holding_invalid` messages to be consistent with other disallowed lints.
* Remove the `(from clippy.toml)` message. I plan on having all the configured lints point to point to a span in `clippy.toml` which will be more useful.
