Don't store lazyness in `DefKind::TyAlias`
1. Don't store lazyness of a type alias in its `DefKind`, but instead via a query.
2. This allows us to treat type aliases as lazy if `#[feature(lazy_type_alias)]` *OR* if the alias contains a TAIT, rather than having checks for both in separate parts of the codebase.

subst -> instantiate
continues #110793, there are still quite a few uses of `subst` and `substitute`, but changing them all in the same PR was a bit too much, so I've stopped here for now.
Do not lint when imported item contains underscore
fix https://github.com/rust-lang/rust-clippy/issues/9942
changelog: [`wildcard_imports`]: No longer lints when imported items contain an item with the name `_`
Test that each config value exists in a test clippy.toml
Inspired by #11560, adds a test that each config option exists in some form in a `clippy.toml` in `tests/` (currently some are in `ui-toml`, some in `ui-cargo`)

Add colored help to be consistent with Cargo
On rust-lang/cargo#12578, a new colored help message format was introduced. This PR introduces the same styling from that `cargo help` message to our `cargo clippy --help` message.
More information is provided in the original PR, fixes#11482. The perfect reviewing process would be that the reviewer installs this branch and checks for themselves, but here are some screenshots, there are some more screenshots in the original issue.
(Note that the actual text may change in the actual commit, that screenshot is just to test the colors).
Also note that the `color-print` version **should always** be synced with Cargo's `color-print` version to avoid increasing build times in the rust-lang/rust repo.
changelog:Add colors to the `cargo clippy --help` output 🎉.
prevent ice when threshold is 0 and enum has no variants
changelog: [`enum_variant_names`]: prevent ice when threshold is 0 and enum has no variants
r? `@y21`
Fixes the same ice issue raised during review of https://github.com/rust-lang/rust-clippy/pull/11496
Add missing tests for configuration options
I noticed that a lot of lints didn't have test(s) for their configuration. This leads to issues like #11481 where the lint just does nothing with it.
This PR adds tests for *almost*[^1] all of the lints with a configuration that didn't have a test in ui-toml.
The tests that I wrote here are usually two cases: one for where it's right above or under the limit set by the config where it shouldn't lint and another one for right above where it should.

Fix large_futures example
The value used in the large_futures example was not large enough to trigger the lint given the default threshold. The example also contained more code than necessary. This PR changes the value size from 1kB to 16kB and reduces the example in size.

adjust how closure/generator types are printed
I saw `&[closure@$DIR/issue-20862.rs:2:5]` and I thought it is a slice type, because that's usually what `&[_]` is... it took me a while to realize that this is just a confusing printer and actually there's no slice. Let's use something that cannot be mistaken for a regular type.
