<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">gitlab-ci: Verify that Hadrian builds with Stack

As noted in #18726, this regularly breaks. Let's test it.

Note that we don't actually perform a build of GHC itself; we merely

test that the Hadrian executable builds and works (by invoking `hadrian

--version`).

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make DataKinds the sole arbiter of kind-level literals (and friends)

Previously, the use of kind-level literals, promoted tuples,

and promoted lists required enabling both `DataKinds` and

`PolyKinds`. This made sense back in a `TypeInType` world, but not so

much now that `TypeInType`'s role has been superseded. Nowadays,

`PolyKinds` only controls kind polymorphism, so let's make `DataKinds`

the thing that controls the other aspects of `TypeInType`, which include

literals, promoted tuples and promoted lists.

There are some other things that overzealously required `PolyKinds`,

which this patch fixes as well:

* Previously, using constraints in kinds (e.g., `data T :: () -> Type`)

  required `PolyKinds`, despite the fact that this is orthogonal to kind

  polymorphism. This now requires `DataKinds` instead.

* Previously, using kind annotations in kinds

  (e.g., `data T :: (Type :: Type) -> Type`) required both `KindSignatures`

  and `PolyKinds`. This doesn't make much sense, so it only requires

  `KindSignatures` now.

Fixes #18831.
