The following DecorationKinds were sub-types of core decoration types:
kStride, kStage, kWorkgroup, kStructMemberOffset, kAccess, kBinding, kBuiltin, kConstantId, kLocation
These only existed for casting (not for error messages), and are no longer needed, so remove them.

And replace the use of`ast::As(Decoration* deco)` with `Castable::As<T>()`.
These were used for dynamic casting, but is now replaced with Castable.

Instead of just having a single `DecorationKind` for the first
derivation from `Decoration`, have a `DecorationKind` for every
decoration type.
Add `Decoration::IsKind()` to test whether the decoration is of, or
derives from the given kind.

Once a `Decoration` has been parsed, it'll be placed into a `DecorationList` and validated later in the parse. In order to create error diagnostics that refer back to the decoration, we need to know its source.
