EXPECT_THAT(xxx, Eq(yyy)) << ToString(xxx);
is a less-idiomatic way of writing:
EXPECT_EQ(xxx, yyy);
The latter also provides a diff when two strings do not match.
Refactor these to:
auto got = xxx;
auto expect = yyy;
EXPECT_EQ(got, expect);
So that the error message clearly shows which one is the generated, and which one is the reference.

This is a public API breaking change, so I've added the `DAWN_USE_NEW_TINT_TRANSFORM_API` define which is used by Dawn to know which API to use.
As we're going to have to go through the effort of an API breaking change, use this as an opportunity to rename Transformer to Transform, and remove 'Transform' from each of the transforms themselves (they're already in the transform namespace).

ReplaceAll() registers `replacer` to be called whenever the Clone() method is called with a type that matches (or derives from) the type of the first parameter of `replacer`.
`replacer` must be function-like with the signature: `T* (T*)`, where `T` is a type deriving from CastableBase.
If `replacer` returns a nullptr then Clone() will attempt the next registered replacer function that matches the object type. If no replacers match the object type, or all returned nullptr then Clone() will call `T::Clone()` to clone the object.
Example:
```
// Replace all ast::UintLiterals with the number 42
CloneCtx ctx(mod);
ctx.ReplaceAll([&] (ast::UintLiteral* in) {
return ctx.mod->create<ast::UintLiteral>(ctx.Clone(in->type()), 42);
});
auto* out = ctx.Clone(tree);
```
This is to be used by Transforms that want to replace parts of the AST on clone.

Prefix the fully-qualified Unique name in TINT_INSTANTIATE_CLASS_ID with :: as there might (however unlikely) be a nested 'tint' namespace.
Move the test structures in castable_test back into the anonymous namespace. This means `TINT_INSTANTIATE_CLASS_ID` needs to sit outside the anonymous namespace, but prevents global namespace pollution.

We're seeing some chrome bots fail unittests in ways that suspiciously
look like dynamic casts are doing Wrong Things.
The ClassID::Of() logic depends on the linker folding away duplicate
compilation unit definitions based on ODR rules. If we were to somehow
end up with different definitions, then we'd have two or more different
ClassIDs for the same T type - leading to issues similar to what we're
seeing.
I'm not entirely sure why/how this could happen - and we've so far been
entirely unable to locally reproduce - but it _might_ have something to
do with the goma cache.
In an attempt to work around this, move the static symbol definition out
of a header-local-static and into the .cc file for each of the types.

Deep-clones all `Node`s and `Type`s into a new module.
Instead of writing a million standalone tests that'll only ever test the
existing fields of each type, I've opted to write the tests using
wgsl<->ast<->wgsl conversion. This means the tests require the enabling
of TINT_BUILD_WGSL_READER and TINT_BUILD_WGSL_WRITER, but I believe this
is much easier to maintain.
I'm aware there are probably gaps in the tests, and that even full
coverage is likely to rapidly rot, so I've also added
fuzzers/tint_ast_clone_fuzzer.cc - a fuzzer based test that ensures that
all AST modules can be cloned with identical reproduction.
I've run this across 100 cores of a 3990x for 4 hours, fixing the
single issue it detected.
Note: Expressions do not currently clone their `TypeManager` determined
types. This is for two reasons:
(a) This initial CL is mahoosive enough.
(b) I'm uncertain whether we actually want to clone this info, or to
re-run the `TypeDeterminer` after each AST transform. Maybe it should
be optional. Time will tell.
