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 95feb99a9d Add Castable template class
Implements `As<Blah>()` and `Is<Blah>()` automatically.

There are several benefits to using this over the pattern of hand-rolled `IsBlah()`, `AsBlah()` methods:
(1) We don't have to maintain a whole lot of hand written code.
(2) These allow us to cast from the base type to _any_ derived type in a single cast. The existing hand-rolled methods usually require a couple of intermediary casts to go from the base type to the leaf type.
(3) The use of a template parameter means these casts can be called from other template logic.

Note: Unlike the hand-rolled `AsBlah()` methods, it is safe to call `As<T>()` even if the type does not derive from `T`. If the object does not derive from `T` then  `As` will simply return `nullptr`. This allows the calling logic to replace the common pattern of:

```
if (obj.IsBlah()) {
   auto* b = obj.AsBlah();
   ...
}
```

with:

```
if (auto* b = obj.As<Blah>()) {
   ...
}
```

This halves the number of virtual method calls, and is one line shorter.

Migrate all uses to use this and the new `unique_type<T>()` and `types()` methods.

Remove the `type_mgr()` accessor. `TypeManager` is now an implementation detail of the module, allowing us to unify the allocation of types and nodes (if we so wish).

The reason being that some tests called parse() twice, which will silently destruct the first parser.
Once the `Module` owns the AST nodes, the second call will end up deleting all the AST nodes. Tests would then perform use-after-free for the AST nodes belonging to the first parser / module.
There's no reason why the unique_ptr can't be returned, which is cleaner overall.

Also rename the test fixture name to include the common part of the test
names, and prefix with Spv. This makes it possible to run just these
tests with `--gtest_filter=SpvBuilderConstructorTest*`

Ben Clayton 165ff1c978 ast::Builder: Make the interface more fluent
Add C++ aliases for the wgsl types `i32`, `u32` and `f32`.

Separate types out from the builder and into a `Builder::Types` class. An instance of this is now held by the `Builder::ty` field. Makes it clear when you are referencing a `ast::type` instead of a constructor method.

Rework a number of builder methods so they take the type as a template argument instead of a parameter. This more closely resembles wgsl (example: `vec2<i32>(1,2)`)

Use PascalCase for the constructor methods, but keep the wgsl-like constructors lowercase to imitate the language style.

Add `BuilderWithContext` so that `Builder` can be truely immutable, and so we can remove `set_context()`.

Ben Clayton 4bfe461646 Big cleanup now that AST nodes are raw pointers
Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
    readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
    they can be repopulated and used again. This is undefined behavior:

> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.

All of these UB cases have been fixed.

Removed all duplicate variables left over from:
  `auto* foo_ptr = foo.get()`
which became:
  `auto* foo_ptr = foo`

Ben Clayton 786bc92002 wsgl parser: Add expect_block(), use it
`expect_block()` takes a start and end token, along with a function to parse a lexical block body.

This reduces code, keeps error messages consistent, and also gives us a future place to try resynchronising the parser so we can have more than one error emitted.

`expect_paren_block()` and `expect_brace_block()` are convenience helpers for providing the start and end tokens for common block types.

This is the first step in improving the error messages produced while parsing.

The `line` and `column` information of `Source` has been moved to `Source::Location`.

`Source::Range` has been added that contains a `Location` interval - allowing error messages to highlight the full region of the error.

The `File` information provides an optional file path, and pre-splits the content into lines. These lines can be used to print the full line containing an error.

This CL contains a few temporary changes that help split up this work, and to ease integration with Tint.

This CL removes the instantiated test suites, instead it tests each of

tests to verify the texture type generated is correct.

This makes the tests a lot easier to read as the string generation for
