Auto merge of #11685 - Alexendoo:clippy_config, r=flip1995

Create `clippy_config` crate, hide internal representation from docs

r? `@flip1995`

The first commit moves a decent chunk of code out of `clippy_lints`/`clippy_utils` into a new crate `clippy_config`

The second commit changes how `--explain`, the book and the site render configuration values. The internal type is now hidden and the displayed defaults are now valid TOML values instead of `Debug` output

changelog: none
