Ben Clayton 26e944bc4e ast: Remove non-group DecorationKind enums 
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.

Ben Clayton 370d20a4c6 ast: Remove the now unused Decoration::IsKind() method 
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.

dan sinclair c7f51b7d3c ast: Support decoration kind hierarchies 
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.

Ben Clayton 34a2eb1999 Add Source parameter to decoration constructors 
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.
