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.
