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 b053acf796 Replace use of std::unique_ptr<T> with T* for AST nodes
This is a minimal effort to fix up the code. There's substantial code
cleanup which can now be done, which is done in the next change.

Ben Clayton 6f58546193 ast: Have all AST types derive from ast::Node
A common base class is required to move from std::unique_ptr<> to raw pointers for AST types.

Also unifies a bunch of similar APIs.

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.

Ben Clayton 35298800a6 ast: Have all decorations derive from base class
This is the first step in unifying the way decorations are parsed - i.e. instead of parsing decorations in different ways based on the predicted grammar that follows, we can parse decorations blocks in a unified way, then later verify what we have is as expected.

`StructDecoration` has been transformed from an `enum class` to a proper class so it can derive from `Decoration`.

dan sinclair eb5d3e147d [wgsl-reader] Allow array decorations to have multiple blocks.
This CL updates the WGSL parser to allow array decorations to accept
multiple blocks. The stride decoration on arrays was turned into a
proper decoration object instead of just storing the stride directly.
