Michael Howell 3a3f70c94e rustdoc: remove redundant item kind class from .item-decl > pre
This class originated in the very first commit of `rustdoc_ng`, and was used
to add a color border around the item decl based on its kind.

4fd061c426/src/rustdoc_ng/html/static/main.css (L102-L106)

The item decl no longer has a border, and there aren't any
kind-specific styles in modern rustdoc's rendering of this UI item.

Most of this commit is updating test cases so that they use `item-decl` to
find the `<pre>` tag instead of relying on the fact that the class name
had `rust {kind}` in it while other `<pre>` tags only had class `rust`.

// Test that we do not currently display `~const` in rustdoc
// as that syntax is currently provisional; `~const Destruct` has
// no effect on stable code so it should be hidden as well.
//
// To future blessers: make sure that `const_trait_impl` is
// stabilized when changing `@!has` to `@has`, and please do
// not remove this test.
